Roughness and Metallic texture generation error, "Texture path is missing."

Bugs

Hi,

We have a problem when we export to glb from 3dsmax with the roughness and metallic texture combination procedure, the exporter complains about this generated texture to be missing.

how can we go about resolving this?

here’s the log:

here’s the screenshot of the material setup in 3dsmax, both roughness and metallic map are setup properly and do exists:

not sure what we can do to fix this.

Thanks in advance

Adding @Drigax for the issue. In the meantime would it be possible to have a repro ???

This might help him having a fix faster.

I can’t upload directly ( new user restriction unfortunatly…), so here’s a dropbox link to download:

What version of the exporter are you using, and what settings are you using for export?
