Nanite mesh has too little vertices for WPO (UE 5.1p2)

I would suggest shadows ignore WPO for nanite. Try displacing only in positive direction from the surface.

hmm is there a way to set things up so shadows are ignored for WPO? Displacing only outwards doesn’t fix the problem, and creates another one as orthogonal mesh parts get separated from each other.

You should model your assets at the very dense vertex resolution. That’s how the system is supposed to be used. Do not use WPO or move the vertices of static geometry in the shader.

If so then Nanite breaks the material vs. mesh independence that we had before. Again, I think if Epic was not able to replace tessellation fully, it should not have deprecated it. Using an older engine is not a solution to me, there are many other things interesting in UE5 that I would not have access to.
