Shapediver uploading different materials map

Hello!

I have been having this issues. The rhino preview window is all fine as I want. But one I uploaded in the shapediver platform the materials differ. There are two plates - one with chamfer the other not.

I am not sure I understand the issue. Could you post a screenshot of the rhino preview as well and point out the exact location where you see different results in rhino and ShapeDiver?
It could be a problem with your outputs, either a big mesh that was reduced by our servers or outputting a Brep which our servers also had to mesh and messed up with texture coordinates.

Hi!
Thank for the reply. This is the rhino viewport. And part of the definition. I remesh everything before mapping any geometry. There are two different plates on the table. But the resulting preview differs. Although in the rhino viewport they are all the same.
