Vertex offset occlusion problem. (Increase Bounds Scale) UE4

[VertexOffsetOcclusionProblem] Right, I’m sure a ton of people have ran into this problem already. If you offset the vertices of a flat object far enough so it mostly occludes the original plane, you get this flickering mess. What I’m assuming is happening here, is that occlusion is based on the depth pass. Step1. Engine renders out a frame. Step2. Occlusion algoritm realises that the depth of the drawn pixel is closer then the position of the where the vertex should be. Step3. Engine culls…

Oh, yeah, what DeepSpace says
