Oh ok. Thanks for letting me know that's the case. I was just assuming something was wrong on either my end or the product end.

So if you are referring to the main unity "console" tab in the lower right window of the image provided no error messages are shown. This is a screenshot of what things look like when importing CADLink on a fresh empty 3D project. No error messages also appear if I close the editor and attempt to reload the project.

So I found out the 3MF files I was getting were not being saved with the options to preserve the materials and color. So now the import of the files is preserving the color of the original files. I would say this is essentially resolved, but it would still be good to investigate the error when trying to create a material mapping.
