Mesh looks glitchy in rendered viewport, why?

Rhino

Hi…,

I wonder why meshes look often glitchy in rendered viewport in Rhino 6 to Rhino 8. In Rhino 5 and in blender (gltf-exported) meshes look fine.

Is something wrong with the vertex normals?

Thanks

Hi Michael - I don’t know… I see that, and the mesh seems fine. Rebuilding the normals changes but does not fix the display…

I do something similar in Blender, but way more subtle, when using AO:

I noticed V5 has the same slightly-visible edges.
