I have the same problem. It is very interesting that when I export the same mesh as a static mesh, it is not visible. However, when I export it as a skeletal mesh with an animation and skeleton, it becomes visible. It’s very boring. I can’t find a solution anywhere. I have already asked on three forums about this and nobody knows anything! There is nothing about it in the Unreal documentation either… @BananableOffense no post process volume was used in this case. But you can check this issue on the Rural Australia plants and leaves. I have the same error on the leaves when I opened in UE5 or more…
