so this is closely related to another question I asked , but it seemed different enough to warrant another thread:
[previous question][2]
and a question from another user that doesn’t seem satisfactory answered:
[other question][3]
please look at the gif, Why is this flickering? I thought Moire effect was only when moving. Why should this happen when standing still with a static mesh?
closeup of the mesh:
im no pro im actualy prety new to figuring out ue4
but since noone is answering ur question …
-sometimes its becouse overlaping mesh
-or maybe try to set LOD (i wont try to explain my sefl cuz ill just make a fool of myself, but try 
)
cheers
My guess: You need to create a LOD for this object.
What you experience here is z-fighting.
The LOD mesh can be a simple gray box - maybe with a texture.
From this distance you won’t see the fine lamellar structures anyway.
