3D Object used by Rhino for material thumbnails?

What is this eyeball-like 3d model called and where can I find it? I want to render some thumbnails of matcap materials and would like them to match the system.

Hi @nxakt, you might look here for the file:

C:\Program Files\Rhino 8\System\rdk_material_scene.3dm

take care not to overwrite it.

Thank you, that is it. And the name is “mat ball”. :slightly_smiling_face:
