Rhino 6 transparent material failed to export to dae file


I’m trying to export an object with a transparent png material from rhino 6 to dae file but it says failed to save since “the file writing plug-in failed”.

This works fine in rhino 5. Anyone know how to solve this?

Can you share a 3dm file with all textures saved with it that fails for you?

The problem is use of special characters in names of objects and materials. Until a fix is published you should refrain from using colon : and backwardslashes \ and & in names.

I reported this as https://mcneel.myjetbrains.com/youtrack/issue/RH-47862

I have tested the fix for this bug, it works, and will be available in 6SR9 in approximately 6-8 weeks
