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

Also, just out of pure personal curiosity, what is the benefit in your workflow to having a densely-tesselated Nanite mesh to then displace, as opposed to simply having a Nanite mesh already in the shape you desire?

This way I can manipulate the texture tiling multiplier at will, I can map another set of textures on the same mesh, use tri-plannar mapping etc. This provides independence between the mesh and the material, which is lost if I conform the mesh geometry to the height map.

If Nanite is working, maybe you could add a tiny bit of noise/variation to the box so Nanite doesn’t automatically compress away all the geometry?

Yes Nanite is enabled, you can see it on the screenshot. Indeed adding noise may help, I’ll try this, thanks for the tip!

Another way to look at it: The whole point of Nanite is that you make the shape in geometry, not in shaders. You should be able to model the geometry at a high enough resolution that you don’t need the shader-level WPO.

I am not using Nanite wishfully here, I am just trying to have an equivalent to tesselation, but that isn’t the case. I think Epic has deprecated tessellation too early, their system apparently is not able to fully replace it.
