Nanite trees. Weird triangles in far views.

Hello.

I occasionally have issues with nanite trees in far away views where leaves turn into weird large triangles when the camera moves away form the model. Any ideas how this can be fixed while keeping nanite?

Things I tried:
Trying all nanite settings.
Changing quads to triangles in max.

Have you tried welding vertices that are too close/nearly at the same spot? Sometimes, when two vertices occupy almost the exact same location, it’s impossible to reliably determine length and direction of edge between them. And it’s likely that Nanite code does that at same point of preparing the Nanite representation of the mesh.
