WCS mapping doesn’t go well with Bella in Rhino 8. In my scene tested it with two simple materials: native Rhino “Custom” and Bella Uber. Color slots in both materials use the texture which has WCS/OCS mapping applied to it.

It might be some scaling issue. The texture preview in Bella GUI is strangely scaled.
