Which AA Setting is the Best for Unreal Engine 5?

- Hello everyone, today I wanted to share some of my experiences with using different anti-aliasing (AA) settings in the movie render queue of Unreal Engine 5. I am interested in hearing your thoughts on this topic and would love to know how you set your AA parameters to achieve good quality without sacrificing too much rendering time. Let me know your thoughts and any tips or tricks you have for optimizing AA settings in Unreal Engine 5. Thank you!

Very useful, love your video!
thumbs up man... this is just super good work, i subscribed.
Ahhhhhhh can anyone help me? No matter what I do I can't get the MRQ to render spatial sub-samples! If I set it to 8 x 1 it only renders 1 sample! Temporal does render though. I've tried everything and can't find any material online. What am I missing??
I just cant get rid of some micronoise that is happening in my scene.. I´ve tried like all AA variations, all the overkilled, default and normal values, turned AA off, then some flickering is happening. Turning AA on, with 1/64 seems to be good value, yet the noise is still visible, mainly on the vegetation that is in the distance. Maybe it could be something with nanite? Cause the scene I am testing is the one called Electric dreams ENV with some of my custom objects. I just cant resolve this issue, rendering it on rtx 4090 so the GPU isnt to blame. Thanks for any advice.
Did you try the new AA method « super temporal resolution » available in movie render queue since 5.2? I got nice results at trying it
@@victorblanchard7774 Thanks I´ll try! But I think I already fixed the main issue by just creating another scene, there was definitely smtng heavy that was causing issues. Thanks anyway, I guess there still plenty of room for testing and experimenting.
TH-cam compression makes it very difficult to see any difference unless you zoom in. But good analysis.
Thank you for you feedback! Also in my screen the difference is not really obvious, it only look little more smooth and less noisy the more sample you add. But honestly, i think you make the difference with the scene, the model, the story telling and the camera angles, rather than aa settings, that just add an extra touch on your render
Does increase in spatial samples provide any improvements? Or can we increase temporal samples by keeping spatial samples as 1
from what I understood spatial samples are essential for reducing jagged edges, especially if objects or camera in your scene are moving. In practice, it is good to try to render few frames with low AA values, and then, gradually increase them to see how it is affecting each frames. That way you can find the right balance need for your animation. In general, 8 spatial and 8 temporal are enough. Usually, I test 2 spatial + 2 tenmporal, 4 spatial + 4 temporal, 4 spacial + 8 temporal, 8 spacial + 8 temporal, and so on. It depends of each scene and also keep in mind that it doesnot do magic: story telling, modelling, materials and lighing are more important.
@@victorblanchard7774 thanks will do some trials
Did you simulate in unreal or houdini? Those meshes look like you simulated in houdini and imported into unreal. Waht format did you use to import? Alembic?
@@pierresdesk hi, the simulation was done in tyflow for 3dsmax
It is a pointcloud converted into mesh and then exported as .alembic
You also can do this with houdini or blender among others
as far as I'm concerned, you never increase both. You choose either one. In your case, you should do Temporal, which also include spatial...
This is a good overview over render settings but unfortunately it will work the same for other projects if they are similar in their composition to yours.
Every type of environment, materials, static or animated actors, effects, camera focus settings, lighting, etc can change the need for render settings.
I think applying general render settings and tweaking it for your specific scene and playing around with it until your find the sweet spot and see if you can apply the same to other projects is the only way to go, kinda impossible to find a one size fits all.
You need to have a fundamental understanding of why you're using the settings that you're using so you can better understand, by the setup of your scene, what settings are relevant, at least that's how I see it, what do you think?
my workflow for each scene is to render just few frames with different AA settings, trying to find the minimum sample need to make the render work fine. Render with 1024 samples is always great but sometime 8 or 16 samples saves you a huge amount of time, and are enough to get almost similar results.
As you pointed out, it depends a lot of the scene you are rendering. From my experience, more samples make a bigger difference if you have fast moving objects and/or fast camera movements.
Maybe the title of the video can generate confusion, or was too long for you to watch all, but I never assumed that there is universal settings that fit for all kind of scenario, on the contrary I explain in my video the exact same thing as you are saying, I mean that it always depend of the scene.
That being said, i also think that it is important to remember that the AA is not a magic setting, and the quality of the output comes first from the model, the light, the storytelling, the materials, resolution, etc. before than the number of AA samples.
If you have any tip to share regarding the anti aliasing let me know, thanks to watch the video anyway 👍
so whats the conclusion, sorry I have no time.. 64/64 ?
It depend or the shot, 64 by 64 may be overkill but why not if you don’t care to wait more time your render. The ideal number also depend if you use Lumen or Path tracer. You need more spatial sample if you have fast moving object or camera. In practice you can start by 4x4 and increase then if need.
If only MSAA wasn't limited to forward rendering. TAA is so annoying
It's not limited to forward rendering, it's just very resource intensive on a deferred renderer & doesn't touch majority of the aliasing in most modern games anyway (coming from textures, shaders).
@@MLWJ1993 IT IS limited to forward rendering. There isn't any commercial real time use for MSAA on deferred rendering
@@mxn5132 You actually could in Unreal Engine, you'll end up shading every pixel that's covered by MSAA by the amount of samples you choose for MSAA though so performance impact was absolutely humongous & the sources of aliasing not from geometry obviously aren't impacted by MSAA...
Hence it's not actually used in practice on a deferred renderer cause people would blame a lack of optimisation for their performance problem...
@@MLWJ1993 Interesting insight.
