I think we need a whole series of "Why CGI can't save the writing/directing". Because people often point fingers at the CGI, say it looks bad, it looks fake, it doesn't fit, it stands out, when they really mean "the writing and directing was so poor, that I couldn't suspend my disbelief and the situation seemed so artificial, it helped me notice all the little inconsistencies in the CGI.

I think they said it perfectly “ they’re not buying the situation and they’re blaming the vfx” Jurassic park took the franchise from a block buster thriller to just another action movie. The original kitchen scene is a good example slow paced and the animals made mistakes and acted like animals it wasn’t just constant senseless action

I love how Clint is always introduced like “Clint is back!” but never really left

I've been saying it for years, YEARS that the dinosaurs started behaving less like animals with every sequel. The reason the dinosaurs behave so real in the first one is simply Phil Tipett's involvement who knew what dinosaurs do and shouldn't do. He wasn't afraid to tell the director that the script is ridiculous when the T-Rex was supposed to lift the whole car with his mouth. Phil Tippett pointed out that a T-Rex simply doesn't have enough neck muscles to be able to perform that action. So they changed it and we got that great business in the car where the T-Rex tries to get to the kids by turning over the car first to attack the underside and squeezing them. There used to be a teaser for an abandoned Jurassic Park project by Ian McCaig and I hated how they animated the dinosaurs, especially the flying ones were treated by the animators as if they are fighter jets, doing barrel rolls, twist, turnsand whatnot. Cg is truly useless without a strong direction or someone with a vision.

Sam keeps saying that he isn’t trying to talk about story/direction but I feel like that would be a good spin off too. Talking about why stylistic decisions are made and how story beats work. Like a combination of screenwriter reacts and cinematographer reacts.

I think it's actually interesting he mentioned that the raptors are like "missiles locked on" because, in the context of the scene, they're wired to follow whatever this like laser pointer points at. So the evil lady points her laser pointer at Chris Pratt, and the dinosaurs lock on. It's not only the context, and that the dinosaurs aren't really behaving like animals-- if anything, in context they shouldn't be. It's just that the context is so unbearably stupid lmfao

I've been noticing that whenever Wren talks in any of these series, he teaches the audience and treats it like a tutorial. But no one else does that. Just an observation. I love Wren. The whole crew is great.

Prehistoric Planet is the most scientifically accurate take we have on dinosaurs EVER Thank you for including the Jurassic Franchise and Prehistoric Planet

That was what made the first Jurassic Park so great: the dinosaurs felt like animals. And that's what made them terrifying: they were just doing what animals do. They were a force of nature, acting like nature acts, whether humans are present to see it or not - which incidentally fit the theme of the movie really well - and the humans were just unfortunate to be in their path. T-Rex gotta eat. Raptor gotta hunt. But in the World movies they feel like movie monsters or theme park attractions, not acting with independence, not following their animal instincts, but following a script to give a certain experience to the main characters and, by proxy, the audience. Ultimately they are created for OUR benefit, so we can watch cool motorcycle chases, and we can sense that when we watch the film, and that's not as compelling, somehow. You could argue that that fits the theme of the World movies, but . . . it still feels meh.

Honestly one of my favorite parts of Dominion was just seeing the Therizinosaurus living a (semi) normal life for like 2 minutes. Not totally insane. More realistic, not moving in weird to ways and not acting crazy. It looked like a wild animal

Ok, just straight up, I was absolutely enamoured by the CGI in Prehistoric Planet. CGI is good these days, but I just found it to be so next level on that series. Absolutely spectacular. But asides from the pure quality of the modelling, texturing, rigging, lighting, compositing, etc. I think the thing that made it step 'beyond' is how it was directed. I seem to recall one of your previous episodes where Pacific Rim was discussed and the shortfalls of the sequel whereby one of the biggest issues was just camera angle. The original was often 'shot' from angles a real person with a camera on the ground could get and it's this limitation that sells it because it ties the imagery with stuff we associate with the 'real'. The problem with so many action-driven movies these days is that they take the full freedom of the CG camera and go crazy with impossible shots, but also from an acting perspective, almost every monster (including Jurassic World dinosaurs) is just that, a 'monster', something unreal with a plot-purpose to be a "homing missile" of pure destruction. If it sees you it's in "seek and destroy mode". Prehistoric Planet took the approach of being a nature documentary and took its reference very seriously. The camera work is very grounded in reality, filmed in the same way as real-world nature documentaries of real 'animals'. The shots zoom a lot (because the film crew don't want to disturb the action) and sometimes even wobble about and the animals aren't always perfect centre in the shot. It's realistic imperfection. But then, the other point is that they really wanted to sell the point that they're not 'monsters'. Even in the real world, a lion or a crocodile isn't always in 'kill mode'. They have lives full of socialising, survival, mating, play, resting and more and the doco puts a focus on these real-life behaviours. Seeing them just doing what any other animal would do suddenly grounds them into familiar realism. But icing on the cake is the eyes. It's one of the first things I saw in the trailer was how good their eyes look, and its the eyes that really sell them on being alive. They're not monster eyes, they're soulful, they have distress, curiosity, love, alertness, etc. The CGI can be amazing, but its the acting and filming that just makes it pop. It's been a long time since I've loved something so much as that doco.

Four years of Comparative Anatomy classes have programmed me to scrutinize animal motility and behavior in films. You guys are right about dinosaurs not behaving like they're theorized to. Jurassic World leans so heavily into the Sci-Fi Fantasy aspect of dinosaurs that it's hard to believe their interpretation could be real. Mixing this fantastical interpretation with the rest of the movies' realistic setting only highlights the dissonance between the two elements.

I think what makes Jurassic Park and The Lost World: Jurassic Park stand out for me is how grounded they feel compared to the rest of the series. The Spielberg-directed entries portrayed them as animals, whereas the later films went in the monster direction. The first two feel like they could take place in “our” world: where the other four have a hyper-stylized feel.

I’m glad you guys talked about the punch zoom and realism. It’s a pet peeve of mine when a movie switched to cg and then physics of capturing a movie go out the window. In a lot of movies, as soon as they commit to cg, the camera starts doing crazy things, flying through windows, etc and it doesn’t have the same impact of something like mission impossible where you can see how it was filmed and that’s an enjoyable part of the moment.

I’m Glad Prehistoric Planet is getting the Respect it Deserves and I’m sure the Audience outside of the Paleo-Community is Glad about it too.

You should do an episode devoted only to Prehistoric Planet. I think it would be interesting for you to explain how they incorporated the dinosaurs into the environment so well

I would love to see them basically prank everybody, by making up an animal with VFX, and trying to trick the media into believing it is a real animal.

My Jump-the-shark moment for the JW franchise was from JW where the tiny Pterosaurs were released from the aviary. Rather than just disappearing off into the forest like animals would, they ALL headed straight for the busiest, noisiest, most unfamiliar part of the island (the public areas of the park) and ALL began attacking the people, creatures 20 times their size, for no reason at all.

The dinosaurs in “Dominion” all walked so stiffly. There was none of that jiggle in the legs like in the previous movies that made them look more real.

I also have some issues with the dinosaur sound design in this one. There are a lot of points where a snarl or hiss stays on the same timbre as the mouth changes position or shape. It’s a small detail, but it makes the sound and image completely detached for me.

It's hilarious that Clint brought up the whole idea of a "CG punch zoom" because it immediately brought to mind the first "big shot" of Cloverfield where the cameraman frantically zooms in on a massive fireball near the city skyline. The intention was fine, but a more "analog" style zoom would have been far better than this rapid quick zoom that 90% of consumer-grade camcorders would be incapable of producing. It's a slightly wonky shot in otherwise incredible movie. And it got me thinking: I'd love to see these guys talk about Cloverfield, and break down some of its shots, like the helicopter crash or the group traversing a building that has collapsed onto another to save a friend. There were so many super small details of that film that I adore to this day.

Glad to see the channel back at full swing!

I really think you guys need to watch/review Walking With Dinosaurs, a miniseries on BBC from 1999. It has a combo of CG and practical effects that really let the series hold up today. Not a lot of people know about it, but I always reference it when talking about how CG and practical can extentuate each other when used correctly.

"We're forgetting it is a lizard." Sam cuts to the core of the issue.

Good creature design is more than just thinking about how the creature looks. it's about asking lots and lots of questions like how does thing eat, what are its relationships with other creatures, what are its relationships with others of the same kind, how does the creature spend its time and so many more. the more answers you get, and the more detailed the answers, the more believable your creature will be in the end. the main reason why the Prehistoric Planet dinos look so convincing and the Dominion ones don't is that paleontologists have been asking and answering those questions for decades and Prehistoric Planet uses them while Dominion doesn't.

Prehistoric Planet, is literally the best documentary ever made, I rewatched it twice, the first time I was so focused on the next level effects I missed the story

It would be awesome if one day a VFX artists react episode ends with "and the Wren in this episode was all CG"

These guys are one of the few defenders of VFX artists, I wish we had more voices like theirs - keep up the good work!!!

WE BACK BOYS!!

Glad to see y’all back on RU-vid. Gave the community a scare man.

Glad they've shown Prehistoric Planet some love, it's the best depiction of dinosaurs on film ever, period. Hope they do a breakdown for Season 2 as well!

Okay, I just have to ask, how have you guys not reacted to the Star Wars: The Old Republic animatics? Those are some of the coolest effects I've ever seen (not to mention some of the coolest lightsaber duels in history). Please react to that in one of your next VFX artists react videos! It would be awesome to see what you think of them.

14:46 THANK YOU! People always say "ah it's all CGI nowadays" as if there's a computer app with a button "create realistic dinosaur" in it or smth. That's a shitton of work right there

What Wren said at 18:38 is partly evident in Gemini Man, where you know it's supposed to be Will Smith, but if he's jumping and falling like he's weightless and gravity affects him differently, then you lose the realism that it is Will Smith fighting Will Smith.

as a huge Jurassic Franchise fan, i really think you hit the nail on the head with the new movies.

I've seen it said elsewhere, but really appreciate you guys taking a look at Prehistoric Planet. It's so bloody beautiful, brings a tear to my eye. Makes me wonder what Jurassic World could be like if it would just incorporate some of that more natural behaviour that PP showcased so wonderfully. Keep up the good work!

As much as I love when they bring guests in… Nothing hits harder than the BOYS reacting to VFX

The point I make about the different design philosophies between Jurassic World & Prehistoric Planet is that the scientifically plausible documentary version of Dreadnoughtus manages to be more colourful, creative & scary than the genetically engineered blockbuster version. PP conveys much more believable animals, which means when they do show off how unpredictable & dangerous they can be, it has way more impact than a raptor with angry eyebrows sculpted into its skull.

I love at the very end Wren throws up the devil horns as he says goodbye and you can see him look at his hand and make a face like 'why is this what I'm doing with my hand?' as the camera pans past him.

Seeing that carno do his little dance was one of the best things I've seen all month.

I'd love to hear more about cgi dino content!!! Specifically the "predecessor" of Prehistoric Planet the "Walking with Dinosaurs" series!! (Just all the dinosaur movies like the 2013 film Walking with Dinosaurs!!)

What you guys point out about subtle animal movements really backed what I feel while watching the original Jurassic Park vs the newer ones. The newer Jurassic Park movies felt so fake despite the upgrade in CGI. Really enjoyed this episode

Im so happy you covered prehistoric planet and I'd love to see you cover it again in the future!

I've always had that feeling you were describing about the later Jurassic movies, and it's a really cool and thoughtful point about the direction and design and motivation behind the dinosaurs. Great comparisons and contrasts

Please check out the early 2000's BBC Series Walking With Dinosaurs, the CGI for the time was great and is very similar to Prehistoric Planet. They also mix in Practical vfx such as puppets and animatronics, i loved watching it when growing up.

It'd be cool to see a "writers react to great and bad stories" idk how you'd get that series off the ground but I'm sure you all could do it.

Hi from Australia. Really liked the conversation in this ep, Corridor Crew. The Prehistoric Planet stuff is amazing because you feel like you're going to witness something for the first time. The unpredictable beauty of watching wildlife. Thanks CC.

Guys, just rewatched Constantine this past weekend and I think the effects still hold up pretty well, you guys should add that to the list!

As a writer, I'm always evaluating a film from a storytelling standpoint, and a lot of films nowadays fall short in this regard because they rely more on spectacle than plot. You can absolutely make a big-budget blockbuster dinosaur film that's visually spectacular, but to put it in the context of a memorable story takes a lot more work - more than it would seem many studios are interested in doing. That's the problem with the Jurassic World movies. You might remember a fun scene or visual effect here and there, but you're not going to remember the story, and so eventually the film itself will be forgotten while the original Jurassic Park is always going to be highly-regarded because it was telling a story FIRST, and THEN supplemented it with groundbreaking effects.

It's weird that they got the truck explosion speed wrong when they went to the trouble of displacing the raindrops with the shockwave.

Jurassic World vs Prehistoric Planet is like Tony Hawk's Pro Skater vs Skate. Both are fun skating games, one is arcady and the other is a bit more realistic.

I would love to see a breakdown of Disney's The Black Hole. That movie scared the life outta me when I was a kid.

love the discussion about suspension of disbelief having a lot to do with design and direction not just vfx, the contrast of the raptor design/behavior from first and last jurassic movies was an excellent way to punctuate the point

I love when they have these longer back and forths, really delving into each topic. Don't get me wrong, the quick high energy episodes like the Ballywood ones are amazing and I love them but to really see them trade ideas and thoughts on these topics is wonderful. I love how in depth they can get and not just talking about the VFX itself but the greater concepts at play, like when Sam talked about the 'little tricks'. Great episode guys keep up the amazing work!

I would love to see you guys react to the effects in the original Christopher Reece Superman movies. Although it’s clearly dated, there is some really good practical work and techniques they used to sell it. Has the same sort of mystique and grand feeling as the og Star Wars trilogy.

My favourite shot from Prehistoric Planet is the close up of that Velociraptor foot slowly stalking forward. That was beautiful.

I remember a bunch of us in Clints server freaking out over the channel being hacked, glad to see its back safe and sound!

17:19 when compared side to side, Dominion dino looks like an artistic interpretation made into a puppet, which goes to show that the render is amazing enough that it looks like something that exists in real life, but the design and the animation departs from a believable living being.

15:45 In order for that raptor to jump onto an airplane that has just taken off, it had to have been going slightly faster than the plane (which can only lift off when it hits around 90-100 mph minimum.) lol

The most challenging part of writing is giving every character in every scene wants, needs, and agency. I haven't seen this new Jurassic Park movie, so I don't know what that dinosaur wants with Chris Pratt. Does Chris have something the dinosaur wants or needs? Does the dinosaur have a vendetta against Chris Pratt? Both things seem unlikely. From what little I know about predators, they have one thing they want to do: Stay alive. They need to hunt to stay alive. It seems like a massive waste of energy to chase after a human on a motorcycle through the streets of Rome when a dinosaur could just eat any human in the city. A van crashes in that scene; presumably, there's a concussed human in the van. Very easy to eat a concussed human in an immobile van. Very difficult to eat a Chris Pratt on a motorcycle. The lack of believable agency for the dinosaurs is one reason the scene feels silly and unbelievable. But again, haven't seen the movie, so maybe it's all explained before the chase scene.

Holy cow! You guys actually talked about Prehistoric Planet on the show! I do agree with a lot of your thoughts on comparing it to Jurassic World, and a lot of people who have seen both have the same opinion, but I also think it plays into preproduction and the idea of a set "vision" for the look of the film. The two shows had very similar scopes and budgets, but there seemed to be a kind of Marvel mentality on the latter of "we'll tweak it whenever we need to, no matter how late into post we do it." It is understandable considering the massive story overhaul that took place after Fallen Kingdom and the Pandemic production schedule, and in fairness, the cuts they made to keep it reproducable aren't all that big in theory. (A bit less to the muscle sims, maybe one less render pass here and there) It's just noticeable when you compare it directly to something like Prehistoric Planet that had a very solid production layout and a very dedicated team of artists and science consultants to each sequence.

16:57 And for me, that's what the original 2 movies did. They were animals. Directed animals at times, sure, but still very much animals. It always felt like those "I can't believe we got that on tape!" moments you get with real animals. JP3 started to lose that a bit for me, and The JW series kept on losing more and more of it with every movie that came out.

Phil Tippett was the master that knew this years ago that's why jp 1 holds up thanks to his character animation for the raptors. 🙏🏽🎬

I'd love to hear your guys take on anything that has come out of Studio OATS as well as the tunnel sequence in Sicario

We've missed you! Hope nothing too damaging was done and that we can get back into our normal swing of amazing content!

This was an amazing episode! Thank you so much! I'm studying for a career in cognitive biology, which is the study of animal minds: how they behave, how the interact, and how they adapt to their environment. Not surprisingly this means that I strongly prefer Prehistoric Planet's realism (that was an AWESOME show) to Jurassic Word's over the top dinosaurs. Having convincing animals makes an immediate connection between the viewer and the action on the scene: we are able to interpret the emotional lives of other creatures - even those that are vastly different from us mammals - and thereby understand and care about their motivation. To me this is what made Prehistoric Planet so powerful. We saw the plight of mother dinosaurs trying to protect their offspring and felt the love, we saw the competition for mates and understood the tenderness of pair bonding, we saw the chaos of hunting and understood the terror. Yes this is what we call "anthropomorphism", and while it must be used with extreme caution in scientific contexts (although it does have its place. I strongly suggest Wild Justice by Marc Bekoff if you want to know more about the cutting edge of cognitive science among animals), it is a really powerful tool in filmmaking. Lastly I want to touch on the subject of intelligence. It's easy to assume that the dinosaurs in Jurassic World are more intelligent because they are capable of navigating our human world with great skill. However, scientifically speaking, this could not be further from the truth. While dinosaurs did have relatively small brains, they are the direct ancestors of birds, which are a species group that is now recognized for extremely high levels of intelligence despite minuscule brains. Corvids (the family that includes crows, ravens, magpies, and jays) reach intelligence levels similar to many primates (although these measures are by nature anthropocentric and, thereby, also in some ways biased). Secondly, dinosaurs were highly adapted to their ecosystem. The behavior observed in Jurassic world is often very dangerous with little benefit. Wild predators are strategic in what prey they hunt as an difficult hunt might not be worth the effort. Predators, ranging from highly intelligent wolves and lions to spiders with brains too small to see, are never ruthless hunters. Their effort is always calculated against the benefit of success. I would argue that the behavior seen in Jurassic World signifies a lack of intelligence due to the reckless behavior of the dinosaurs, while Prehistoric Planet instead more accurately shows the subtlety that dinosaur minds were likely capable of. Prehistoric planet shows social skills, group coordination, problem solving, and parental care: all traits both seen in modern birds and which require significant intelligence. Let us not judge other creatures' intelligence on metrics that center on ridiculous standards of being able to navigate machineries and cities. Otherwise we are guilty of anthropocentrism: acting as if human intelligence is the gold standard for all other forms of intelligence. Intelligence should be adapted to a creature's way of life, and that is exactly what is brilliantly shown in Prehistoric Planet. We humans also have our own limitations and abilities dictated by the environment to which we are adapted. Yes, we are a highly *adaptable* species, but that does not make us a metric for measuring other intelligences. I hope you found some of this interesting! And thank you again for the marvelous episode!

I really liked the last part about "directoring " and VFX collaboration

Glad to see my favorite channel back up and running. Couldn't help but laugh though at the irony of the sponsor segment.

IMO, from now on all the next paleo medias will have to look back at Prehistoric Planet to get inspired by its animation nuances, such as they did when Jurassic Park (1993) was released, 'cause UOW, that's so superb and realistic. As you said, it's not about the CGI quality, but its concept. I'd love to see u guys reacting about other scenes from that, and also to take a look at the 99 documentary "Walking With Dinosaurs", produced by BBC. It was the first time we saw great cgi dinosaurs out of the jurassic park franchise, and it was impressing, especially 'cause it was a 99 TV Show with a lot more dino time screen.

If I'm seeing it correctly, it looks like the raptors feet motion is entirely divorced from their actual movement forwards. There's a bunch of places where their feet seem to be almost sliding forwards along the ground even as they're being placed down. Given those feet are pushing backwards to propel them forwards that looks super weird. Their progression forwards is just too smooth and seems almost like a fixed rate, too, for something propelling itself by running.

Another entertaining episode guys. On the guy walking into the room on fire.. the reflection in the door glass appears to be showing the right arm that we can see also as opposed to the left arm that we can't see... unless he is swinging both of his arms in tandem as he walks :)

There were some scenes in Constantine you guys might want to check out. The VFX on the dragon breath fire in the beginning was pretty dope and it's some other visual effects in there I think you guys might want to check out. Awesome video like always.

I feel like the other problem with the raptors was the lack of consistency. They caught up with a motor bike but were outrun on foot in previous scenes. Makes you think something is off.

Suggestion: The Sandman on Netflix, in particular the crow "Matthew", being voiced by Patton Oswalt. In the outdoor scenes in episode 3, "Dream a little dream of me" it looks outstanding.

2:58 A nice touch is that they made the rain move towards the camera with the shockwave of the explosion. You can see it well at the dark areas of the door.

Holy sh*t! TY so much for talking about Prehistoric Planet! I hadn't previously heard of it, and that is not the kinda show I want to miss out on! It looks so cool! Y'all have introduced me to so many movies and shows that I woulda otherwise never heard of. I can't thank y'all enough for that 🙏

I don't know if y'all done it but can y'all do an animator's react to "Star Wars The Clone Wars, The Bad Batch, Rebels, & Star Wars Visions?" I found it very impressive and interesting on their progress over the years and how they also took a new direction regarding animation style.

We got Prehistoric Planet LET'S GOOOOOOOOOOOOOOOO!! I'm so delighted you guys were able to do some more dinosaur stuff; that breakdown of the steps needed to produce realistic anatomy & skin was quite insightful! If you'd like some more content on the subject of too much/too little creature work, the program 'Dinosaur Revolution/Dinotasia' could be an interesting choice in more stylized dino depictions; for that matter, it could be worthwhile to look more closely at how Jurassic Park's own dinosaurs have evolved from film to film.

Love the resident evil lab door sound effect transition guys!

The velociraptor. thing is that the they don't breathe. So it doesn't feel like the velociraptors are real, it doesn't feel like they have to make a calculation of how much energy they spend chasing the character and how much they're going to gain from that. So it doesn't feel like they breathe or or after him to eat it feels like they're a robots. Animals don't chase you till the end of the world because they have to save some energy for when they catch you because they might have to fight you. So that's what makes it not real in my opinion

I agree with the first film the dinosaurs being animals; the clip you added with the two raptors entering the kitchen, and one takes a slight warning snap at the other, was absolutely relatable: my brother and I simultaneously saw it amusingly as the behaviour between his dog and our mom's more aggressive dog.

The funniest thing about the last JW film, is the fact that they actually had scenes of dinosaurs acting like animals. There is an entire prologue, which they cut out of the final film, that shows dinosaurs, during the cretaceous period, acting like animals and it looks magnificient.

Love this channel, and the crew.

glad to see you guys back

10:28 "Good Worm FX" - Clint 2022

Another problem that I saw for the velociraptor chase was how they were acting against the surface, in order to give them a sense of speed they make them move their legs very fast, but on asfalt with claws they would have more of a grip making them run a different way. You can even see at the beginning of the chase a moment where the raptor is running too fast compared to the street giving it a scooby-doo feel.

GOBO'S!!!!! I've been wondering what this type of shadow technique is called. Thanks Wren 🧡

Can't believe we're at 80 EPs, thanks for all the great content Corridor!

We need a Corridor Reacts to their channel being back! Let's goooo

This is literally the most interesting channel on here, I’ve learned so much watching you guys I remember I started watching on like the 13th cgi good vs bad and never missed a vid

I love you guys, gladd to see you back

How cool would it be to compare these 2022 Prehistoric Planet shots to the OG version and award-winning 1999 Walking with Dinosaurs series!? See how far the genre has come and compare the two approaches to ‘realistic’ dinosaurs!

Thank you for doing Prehistoric Planet! I look for more analysis of its effects!

12:25 - Gobo is a contracted form of phrase “Go Between”, since the gobo is typically inserted between the light and the subject being illuminated.

I can’t really put my finger on it but there is something about maybe the texturing of the raptors in the recent Jurassic Park film that really made it look like an older generation of CGI. That shot were you have a side by side of the Jurassic Park and that Dino nature series really highlights that

this was a fantastic episode!!

great breakdown on the direction VS. CGi at the end there, really insightful. that's why you guys are the best!

The issue with the burning zombie? Is he looks like he's walking to the bar after the waitress brought him the wrong drink. It's not a zombie walk, it makes it 2000x worse.

Great to hear the term GOBO still being used. They get inserted inside the spot at the focal point (and burn up quickly) but if you want those parallel rays (on stage or cgi) then the pattern is outside the lighting instrument and then it is a Cucoloris. Easier to make and won't burn up (on stage). Obviously, with cgi you can put your image in a spot or for Infinite lights map it to a plane. Plus you can bake in the sharpness on the image. Thanks, this info has just been lingering in my memories for decades.
