Cel Shading material causing flickering shadows

Hi,
I’ve been trying to find a good cel shading postprocess material, I’ve tried some but the one i liked most is this one: https://www.youtube.com/watch?v=ry-E3QmpIBU

There is one issue though, with every cel shading material I tried (on newly created 3rd person project with no settings change, just few assets imported) I always end up with some form of flickering.

I uploaded two videos, the first one is with screen space, at first it looks fine but with certain camera position you can see the flickering. It’s not shown in the video but if you zoom in enough you can see the flickering almost everywhere

Second video is with Lumen, I don’t know why it showed it like that at first (first time it happens) but when I started the game it “fixed” itself, you can see the shadows flickering on the wall and the cube

I’ve tried all the solutions I found on the first page of google but none fixed it completely, only make it less worse (one of which was switching to screen space).
Is there any way to solve this? Or a Cel Shading material that doesn’t do this?

Hey, did you found a fix for that? I’m having the same issue

Hi, no I haven’t found a solution yet :frowning:
