I am trying to render some Nanite foliage btue the TSR is giveing me a lot of grain/noise in the foliage shadows. If you focus in the trees and grass you can see them clearly.

[https://d3kjluh73b9h9o.cloudfront.net/original/4X/2/6/d/26ded1d67001e766b95acb17dd4824ff14443113.mp4](https://d3kjluh73b9h9o.cloudfront.net/original/4X/2/6/d/26ded1d67001e766b95acb17dd4824ff14443113.mp4)

What to do? what is the definitive solution for a crisp and clear render for a Virtual Produciton/InCamera VFX live recording?

Did you try other anti-aliasing methods?

I know… I don’t have a solution. It’s related to foliage / Nanite / Lumen. I assume it’s going to improve…

It has to be a way sisnce they releases Fortnite in 5.1 and there is no grain in their foliage as se can see here:

That would be a very non-vanilla version of the engine. I also don’t see any moving foliage.

My grass dont move as well, but the noise in the TSR is just too strong.

I just downloaded the [MAWI Redwood Forest | Unreal Engine 5.1 Nanite](https://www.youtube.com/watch?v=trVgBpSAVC8&ab_channel=MAWIUnitedGmbH) Demo and they managed to avoid this noise in the shadows, i just need to know how =z

I know they are very into ‘early Z pass’, you might try that?

> Enabling Early Z pass on Masked materials in render settings is giving me a huge boost in a scene with tons of foliage. However, it is unable to render 2d sprites in some areas while causing jagged shadows of characters in one area. I initially thought that the jagged shadows were being caused because of something else. Turning Early Z pass off or setting it to automatic fixes the shadow issue but brings back the overdraw and shader complexity. My questions: \>I have been reading up on early Z …

I just though, that’s probably not the answer, as it’s enabled on a project wide basis…

Maybe contact them and ask?

Well, I commented on their video asking for a solution LOL aahahha.

Besides that, [I rendered my scene](https://www.reddit.com/r/unrealengine/comments/zm7da8/alder_forest_more_updates_on_my_nanite_forest/) in 4 hours with MRQ and it look soo nice! Just having a little problems with some foliage shadows bumping from nothing in the begining, but I am pretty happy. ([HD Version](https://www.youtube.com/watch?v=2TOGplorcak))

Now in realtime it is just impossible because of this current problem in the foliage shadows.
