Hey Guys,
is there a way to fix grass flickering in Unreal, I have searched but haven’t found answer that actually works.
Thank you!
I also face this type of problem.
Flicker how?
Usually when you see things appearing and disappearing you either overloaded the rendering pipeline with too many tris, or you have some occlusion issue.
Flicker, like noisy textures rather than sharp textures.
Is temporal anti aliasing on, and is the mip for the transparency altered?
Temporal anti aliasing is on and i have not altered the mip for transperency.
I have attached what the result of my test render looks like.
Can’t see the image from mobile.
Either way, if you haven’t changed the mip for transparency you may need to.
It depends on how thin and detailed the alpha mask is.
The engine will always try to bump the mips down, so you end up with fuzzy AA artifacts.
Usually an offset of -2 is more than enough to fix it.
Would this also contribute to a very noisy render?
Really depends in the quality of the alpha map.
The fuzziness you describe is most common on hair cards rather than grass… but it is possible on anything that the engine shrinks/compresses more than it ought to…
