I get this question all the time now…why use the Octane render plugin for Unreal Engine when there's Lumen and the in-built Pathtracer too. There's no simple answer so I thought I would do a rundown of the pros and cons of each.
I'm going to break these down into four categories… Quality, Speed, Accuracy and Compatibility. I'll be using the 1hour unreal engine scene I put together on the last video as an example and have rendered it with lumen, pathtracer and octane so we can see the results.

I used to exclusively use Cycles and Octane in Blender until I made the move to UE in 2020. I do a lot of large animation projects for heavy industrial clients with HUGE meshes and found that being able to use datasmith within Unreal was a massive advantage vs my previous pipeline. I still do use Octane / path tracer for certain client images (static shots mostly), but i would say that 8.5/10 they are more than happy with Lumen + a bit of Davinci post prod work. I have come to absolutely love Unreal, it is awesome to have the versatility to choose multiple rendering methods on the fly to see which one really suits your specific project. It's also really hard to beat a 4200 frame 1080p animation coming out of the pipeline in less than an hour! And its free! Keep up the good work!

@JoshuaMKerr 2 года назад

Youre absolutely right, theres a tool for every job and we really do have a vast array of choice now plus speed! Thanks for the awesome comment.

@melomaniakjm Год назад

Totally agree…speed is key and the quality you get with Lumen is more than enough for 90% of my projects. And when it’s not we have alternatives, incredible tools we have access to these days.

@joshuajamesharvey Год назад

Just a tip on wigglies in the back of your octane render. When you see 4x4 squares of missing information (they'll always be a dark square) that's caused by the min adaptive samples being set too low. Essentially those squares were black when adaptive sampling engaged and we're immediately turned off.

@JoshuaMKerr Год назад

Oh absolutely. However its a toss up between that and increased render time. Its all down to what youre happy to accept in your work. I dont mind a little noise sometimes as long as I know how to fix it.

great comparison, I really like using both Lumen and Octane for stills and video, I think it's great that unreal offers a diverse render pipeline, reminds me of blender but better

I’m trying to add octane to my UE5 pipeline, because I’m interested in all the AOV options it gives. I’ve tried it with simple scenes and it worked, but now I’m trying with a more complex scene like the Matrix city, and after loading my scene and UE5 working perfectly, I click on"load octane", then it takes like 30 minutes preparing textures, and then it crashes. I think that it crashes when it tries to load the materials. I tried several times already, never been able to view anything in the renderer yet. Not sure if the matrix city is too complex for octane.

@JoshuaMKerr Год назад

Yes, this is because Octane doesn't utilise things like nanite and virtual textures. Matrix City Sample would be too geometry and texture heavy to render.

@Mac_Daffy Год назад

Hey Joshua. OTOY now released Octane 2022.1 for Unreal Engine in version 0.62 and it now comes with OctaneLightmass, a first version of the octane lightmapper for Unreal (experimental). This GPU path tracer is free for a single GPU but the plugin can use multi-card setups. Using Lightmass to bake those textures with Octane you could get the Octane look in a real-time engine and combine it with Lumen etc. Would be very interested in your take!

@JoshuaMKerr Год назад

The motion blur problem is that with the unreal plugin Octane doesn't calculate the motion vectors. There is an Octane 'integrated mode' that uses unreals viewport motion blur...but it really does look like garbage haha. Good point about multi GPU although I believe that's a paid for option

@Metarig Год назад

in the new version, the path tracer supports new things like decals , volumetrics and nanite, and also if you crank up the sample to have to wait the same time as octane wouldn't you get a better result with the path tracer? in my opinion, it would be great if in the upcoming versions you can choose which portion of the scene should be path traced and which portion be lumen.

@JoshuaMKerr Год назад

That would be a good feature. I liek the path tracer in Unreal a lot more now than when I published this video and have been using it a lot more recently. It still has a few things it can't handle (hidden shadow is one of them) but it's only a matter of time. Octane still has a lovely texture and overall result so I would have to do another test to see how they compare now.

@Tycholarfero 2 года назад

@samuelenslin1850 Год назад

Thank you for the comparision. I don´t think the scene you tested it on does it justice though. We´ve used Unreal extensively with only Lumen (when necessary) on a documentary and it more than exceeded our expectations. While there were SOME artefacts (shadows mostly), I´d much rather troubleshoot these on a 20 minute render vs an 8 hour render and if need be render in layers/fix stuff in comp... We have only tested it on a narrow scope of projects yet, so my opinion might change still...:)

@JoshuaMKerr Год назад

Cant say Im a big fan of Lumen but glad its working for you. The scene didnt take 8 hours with lumen though, that was octane. Some of these things can certainly be fixed in post or in layersm Davinci has excellent features for flicker and noise for instance. But sometimes thats extra time spent on what should be working already. Bear in mind I am focussing largely on doing as much in engine as possible and rendering beauty passes for editing and grading (maybe not even that)

@samuelenslin1850 Год назад

@Joshua M Kerr Oh yeah, I got that octane took 8 hours. I think th scene itself looks rather gamey and I've seen and produced Lumem scenes that looked way more realistic. I also still think pathtracing or offline rendering GI and reflections look better, but in most cases I'd rather spend more time on improving the scene through lighting and shading and composition rather than better GI... I also had those fireflies with pathtracing and I know some of them came from using the hdri wrong. Really depends on what client you work with, if uts someone who notices every flickering pixel, you might be out of luck sometimes with Lumen. Just saying that I both had completely fine 4k renders AND most of the times it's not noticeable enough if I DO get issues...

@JoshuaMKerr Год назад

I'm only using Unreal for my own films so I guess Im the one who gets fussy over flickering pixels haha. Youre absolutely right that the scene doesnt look very realistic, it was part of a 1hr challenge (thats my excuse).

I have a valve index system and I’m kicking around the idea of getting a vive tracker 3.0 and doing a live green screen composite.

@JoshuaMKerr 2 года назад

You certainly could do that. Maybe try an exr sequence first so you have a single video track with embedded alpha. You can also go into project settings and increase the amound of GB to allocate to playing media. look for the IMG Media tab. Also...under the preferences in your media track in sequencer there is the option to specify pre roll and post roll frames. This is worth fiddling with.

@robinreso6240 2 месяца назад

As being a beginner the fast render times of unreal are really godsent. getting tired of optimizing every part of my scene just to shave off a couple of seconds. Understand that scene optimization is key... but all that fiddling with setting takes away from creation.

I don't do any kind of rendering, but I was curious what the results would be if you did a time-normalized comparison.

I'm not sure if there would be other constraints that would prevent this, just curious

Certainly an interesting thought. Although in practice it would be tricky to set up the render to make sure it took that amount of time. My guess is that beyond a certain point it would be a case of deminishing returns.

This is one of the advantages of Unreal... today, many of us who work freelance with our own equipment, making an 8-hour shot for a client is terrifying, no matter how good quality it is, today everyone bets on the fast, the immediate with a good quality and in that Lumen and Pathtracer are superior to octane, vray, arnold, redshift and etc etc... one of the strongest points of unreal is undoubtedly the speed of realtime.

Thanks for this. I've seen both of these videos before, but they aren't really what I'm discussing, which is and image stability issues in renders, which are easily visible in the scene I'm using as well as in the two videos you have linked. You're right though, if I decided to compare things like realistic lighting, material handling, reflections and traslucency then I would certainly design something more realistic and useful to highlight these things.

@monocore 2 года назад

Why on earth would you use neat video instead of the renderers own denoiser? The built in denoiser usually has data passes to help with the noise, you're giving up all that extra info just rendering and denoising it in post.

@JoshuaMKerr 2 года назад

Simply put, I'm not keen on the result. Best case scenario of course is just to sample until the noise is gone. But failing that (maybe due to the render time) especially in the case of Unreal the internal denoiser is way too heavy and gives you no control so denoising in post can be a good option if needs be. It is less necessary in the case of octane because there are deeper options. Having said that I just cant bring myself to use a denoised video render from Octane. Sometimes its all down to your personal aethetic. For instance I tend to add grain to my films...call me old fashioned ;)

Lumen is enought until we will be able too get enought of power to work with Octane, (two decades whatever, when its better then its better) in gaming you can get much better visuals when there is space for using more other technologies at once as Nanite, Realistic physics etc + Lumen+ better textures (vram), models this all will give you better visuals then only pretty ray tracing itself which realy costs still a too much of a performance . for the sake of lighting only, especialy physics is even downgraded from the comparison with past generations and it feels afwull as hell as gaming expyrience. Octane is much more demanding of course but its probably worth to put down Ray-Tracing and Path tracing completely for the sake off overall balanced visuals and interactive expyrience (the most important thing for games, not for movies) and during that time working on tools optimized directly for Octane. Its just better, to be honnest it looks "real" to me, while ray tracing does not it does realy weird over the top things realy often and its forcing you to even downscale your resolutions for sake of actualy playable frame even with GPUs for more then 1000 usd in one case for 1600usd + . which is ridiculous waste of power.

Lumens can work for a lot of things like comedy shows or other things where realism isn't important. At that point Lumens is (to quote David F Sanberg / Ponysmasher) "Good enough". :) If I'm doing an explainer video or a training video, I don;t care if it's amazingly realistic but for a proper film or an advert for a serious client ... then yeah, Lumens is kind of poop. :)

A big strength of lumen is that it works in real time pipelines too. Great for led walls. I've managed to get some good renders from lumen recently but if a project can be offline rendered with a path tracer then I'd definitely go for that.
