how grass works in Ghost of Tsushima 

My grass obsession continues.

I never thought i would be so invested in grass of all things

the most impressive thing is that they did all this work because they really truly understood the atmosphere and image they were trying to convey with the game and they knew this was a significant and impactful part of it

Honestly best grass I’ve seen in gaming

That grass also looks very tasty. The goats of Tsushima will definitely appreciate :o) Jokes aside, this is one of your best vid. I think you found a good pace and structure for this type of content.

Ive been meaning to research that GDC talk but a lot of the concepts felt inaccessible on my first watch through. This has helped a lot!

"What makes the green grass grow!?" "Vertex shifting bezier curves and a scrolling Perlin noise texture!"

half of my playtime in this game is staring at the vegetation

The amount of planning and problem solving it takes to make games like this blows my mind. They did an awesome job

I predict a 'so yeah grass is pretty cool' at the end

The fact you reach out to feel like grass as you walk makes me all giddy when I see stuff like that in games

You know what's crazy? The PS4 Pro is known to be loud even when cleaned, but throughout my entire playthrough until Platinum of the game, not once have I heard my console emitting any noise I'd usually hear when playing games such as God of War, Ratchet and Clank, and Days Gone. It _does_ make slight amount of noises during cutscenes but that's to be expected, but the gameplay experience itself is so silent it's quite jarring. I remember sometimes putting my ears next to me console to hear any noise but nope, nothing. Add the inexistent loading screens to the mix and the praise goes to Sucker Punch for pushing the console to its limit as efficiently (and quietly) as possible.

That's really interesting and it's crazy how much work goes into making something as mundane as grass look right. They did a great job and I especially like the accuracy of the clumping.

It's great to learn about things you haven't seen before.

Beautiful, technical, no way in hell am I even thinking about attempting any of that in my project. I felt dizzy just listening to this commentary.

I just ran across your channel for the first time and it is amazing! I love how you explained how something simple like grass can be infinitely complex within a virtual world. Seriously, you have an amazing channel and I will be a viewer for as long as you continue to produce content (as I just subscribed)! I hope that you produce more content on small details like this (eg. water physics, shadows, dynamic weather systems etc. within videogames), I think small details within videogames could be your “thing” because you teach it in such an engaging and interesting way 😊🙌🤩

Just WOW! How much thought and technical mastery was needed for the grass is inspiring and astonishing!

I've just discovered your channel, really loving the content! It's very well explained, so that even a relative layman like myself can understand. Also succinct enough to keep my interest without going too long. Well done!

This is a TL;DW of the GDC talk. Thanks!

You're videos are so helpful. I'm trying to master environment art, but before that I must master 3D vegitations. This is the kind of level I want to achieve where you truly perfect your area of interest. Great explanations , research, and details. Thank you.

I like this video because it's more in-depth and technical than your other ones

Ya Ya! grass is grass and it's pretty cool. Touching and feeling it also crazy cool.

Thank you! the implemented *dynamic movement* for its interactive dynamic environment "guiding winds", for its visual direction, was Ghost of Tsushima own identity. since it inspired by Akira kurasawa. hope more people get to watch this.

Absolutely amazing video! Loved the attention to detail, the info and the straight to the facts theme!

this is really interesting stuff, for something that you might hardly think about in game the developers put a lot of thought into it. correct me if I'm wrong but this type of work falls under the role of a technical artist, right? rather than purely the environment artist?

I got so inspired that I went outside and actually touched grass

This is really interesting! Thank you for explaining this!

Amazing. So many good ideas in here. I really, really want to see if I can reproduce this grass behaviour. Especially the LOD blending, not sure how to accomplish it but it seems like a great challenge.

I remember watching the gdc talk about this, I was crazy invested for some reason

When touching grass in a videogame is much cooler than IRL

I hate how we have to use doctorate thesis levels of algorithms just to render grass

The facing to the camera reminds me of the old games that spin trees or character sprites to face you. Mainly thinking of racing games, but they are the games that tend to perform extremely well for their graphics.

Thank you So much for ur ti and support

"It's about grass it's about unreal, we stay hungry we devour art station" - Art Station

3:20 You could probably fix that Plain looking ground aswell by adding an LOD with some streaks of coloured green, perhaps even add a reflective surface for some shine.

Zelda's Grass was made in a similar way too. Polygonal grass looks like the future since GPUs are getting better and better to render Polygons but at the same tame, overdraw still a massive problem when using cards. Creating Procedural Mesh for foliage does not seem like a big trouble, but I guess It would be a pain to use it in Unreal, for example, since I don't think Foliage Tool would be usable, requiring us to do GPU instancing manually (Maybe I'm wrong, IDK). It looks like a lot of hard work.

Cool. Thanks for the explanation!

you could also explain how the leaves work, they interact with your interactions, wind and the environment

Thank you this video was great

Just found your channel, I will be bringing this all night lol

this motivated me to go out and TOUCH GRASS

When you get genuinely interested in video game grass, it might be time to touch grass.

Damn bro. Give this more views amazing vid. I'm subbing

Wow great insight thanks 👍

Can you please cover grass of genjin inpact as well?

The quality of GoTs open world cannot be overstated. It is one of the most alive-feeling environments ever produced.

That grass was a staple of the game

very cool video ! Thank you

I admire their computational efforts. but the challenge is when the quality of realism increases, the required level of art grows simultaneously

Developer: *Folds Grass to save ressources* Manager: Im not even mad that's amazing!

my first thought when i played the game was "how is this not super expensive to run?" they did a great job optimizing it unlike some other AAA developers. It shouldnt be something you congratulate since all games should be optimized. but its getting rare nowadays.

Incredibly informative. As soone with no background in soft other than so Nice tutorialgh school band, I completely understand everytNice tutorialng

Very interesting stuff, great video

To make it easier to understand, you can change "frustum + distance culling" to the ordinary explanation of what it actually is - checks if objects are in the camera view at all, and not too far away. These are small things, but they add up for average user and make things harder to grasp. Nevertheless, a great video.

Would love to see what this looks like in the engine, how how all the nodes are connected in the material (and what nodes are used), and in blueprints (if blueprints are used). But, it doesn't seem to be something people are willing to share.

I was very interested in grass when ghost of tsushima came out ty for the awesome vid!! Can we also a have video of fonts in video games? I feel like no one really talks about it.

It's so beautiful 😍 most beautiful game of all time this coming from someone who plays all AAA games that hit the market.i literally fall asleep and leave my headphones on cause the sound effects and music are perfection. Need a sequel right now please.i really really need it please I cannot live without please please please

Thank you for not clickbating this. Other ytubers would stretch this to at least 15 minutes...i was preparing to be irritated when I clicke in but was pleasantly surprised!

lol the way you said "so good"

FS series would be a perfect candidate that can implement these techniques.

it just works

great new knowledge learnt

bro touched some grass and motivated to not touch it again just to make someone able to touch the grass virtually and realistically

You should make a video about how window cubemaps work in video games

I'm curious if because parts of the grass are procedural, if some parts of the map also have slight variations to them across peoples consoles although I doubt thats the case. Great video!

Oh snaaap. This video is awwwwweeeesome! 💪

It’s amazing that multiple draw calls from using grass cards gets so expensive, that it is cheaper to render every single blade using geometry.

Now I understand how the grass in my yard works

Never played this game, never seen any real gameplay of it either. Yet here I am, watching a guy talk about how the grass works. Crazy how life works out.

amazing video , could I have the link for the back ground music

Unreal Engine 5's new Nanite Foliage seems exciting now!

Great video

Thank you for the eli5

damn i did not know so much thought went into it!

One game that did grass insanely well was far cry 2. Can't really describe it but it's just so simple yet sooo convincing

Sometime in the near future we will have a photoreal video game who's graphics consist entirely of perlin and voronoi noise textures

this reminds me of the grass tech from outerra

Grass is pretty cool

I'm allergic to grass, I think I got healed by this video

A whole video about grass S tier

Since grass density is a major gpu hog, and also what much of what makes nature exteriors look beautiful, it makes sense for developers of AAA titles to put a lot of resources on developing new techniques for its optimization.

"so what was your assignment during all those years of creating the game" "grass"

I think you can notice that stuff is loading when he turns the screen quite fast. That everything behind the camera is not fully loaded, if I understood it correctly?

amazing, also it is such a great game

When is it out on PC though

kind out of topic but im once found a game with advanced grass setting distance, density, and scale. the most performance hungry is density. im max the distance value and keep the density low and make scale more a bit to fill the empty look space. its beautiful and it eat very less performance, almost same like the max setting. but all im see in most game the grass is not the problem what it make good but how it look good.

needed to go learn by acting!

That really makes me want to touch some grass

Rendering grass is one thing, using grass as a map guide in combination with the wind is next gen stuff.

do more videos like this

man i love grass

And now we just wait for the pc release to see (hopefully) more grass

finally, more grass

God please let this be ported to pc

This guy made ''Touch grass'' next level

How do they do all this??

How can this be even rendered in real time. It seems a lot more to process. Isn't the shifting verticles harder to calculate than a simple change in LOD?

When you are so damn bored that you start learning to appreciate the art of grass

Does ue5.1's nanite for grass nullify all the procedural effort.

How does it affect performance tho?
