Weird shades in rhino render

I downloaded an Pikachu obj file from If I check it in Meshlab it looks ok. But the rendered image in rhino has dark shades all over it. How do I get rid of these shades?

I do not see these shades in other obj files.

Hi Aad,

It’s probably fixed with the command _RebuildMeshNormals.

Does that help?


Yes, Thank you, Rebuildmeshnormals fixed it.

Great tip! I saved that one.
