UPDATE: Fixed. See:
I have a detailed cylinder in a Skeletal Mesh:
But if I move just two meters away, it starts to flicker (settings are all set to “Epic”):
When it’s animated it’s even worse. Notice that when animated, with the camera close to it, it’s fine.
I tried scaling Bounds Scale to 10, but it didn’t make any difference:
LOD is still LOD 0.
Any way to avoid this?
Looks like z-fighting, you sure you don’t have overlapping meshes there?
100% sure no z-fighting there. Here’s the cylinder mesh: SM_CylindersDetailed.fbx (25.3 KB)
Test with only the cylinders (the above FBX) - it flickers so badly:
I fixed the flickering partially by making the cylinder smooth and baking the bevels as normal, but now I lost the sharpness of the bevels - it’s supposed to be sharp because it simulates real grinding industrial machinery.
NOW:
BEFORE:
UPDATE 2: Just tested with both Godot 4-alpha12 and Unity, trying to replicate the same lighting and AA conditions, and the model does not flicker neither in Godot nor Unity.
I wonder what should I tweak in UE to avoid this?
Someone on Twitter told me it’s Moiré Pattern.
It should be supposed to be gone with TAA, but it’s already using TAA.
Then I increased Screen Percentage in the Post Processing Volume and it solved it, but then it’s not ideal, since it caused a huge performance hit. So I would consider it as still not solved 
Just got it a 100% fixed. It will be a game, so I need performance. I changed settings to:
Keeping it here for others that in the future may stumble upon the same problem. (Why can’t I mark this reply as the topic’s solution?).
