Additional Notes

This could also be caused by bounds of the mesh which is currently not exposed and not having bDisallowNanite exposed.

I have the same issue

Even set it up as two sided and it doesn’t help. I think its something to do with the original mesh that in effect doesn’t move and the line of sight to that and the moving mesh is through the material.

The main issue with it is that we dont have access to BoundsScale and sense we cant set that, the default scale is really small and causes it to unrender and be flickering from what I can see.
