Rhino 6 Mac - Export 3mf of object with texture fails

If I try to export an object which has texture assigned to it, and I check the “Save Textures” option, I get an error that the export plugin failed.

Is exporting in 3mf format of an object with texture supported?

There’s something wrong here.
Windows works provided the material or texture is applied to the object. Layer materials are ignored.

In Mac, the color seems to work but the picture based material is giving an error.
We suspect because how file paths are different in Mac and Windows there’s a problem there.
The developer is looking at it.

I’m looking into this now. See https://mcneel.myjetbrains.com/youtrack/issue/RH-59547 to track progress.
