Hi fellow sketchfabers,
I recently tried to upload my first model to sketchfab that uses 2 uv channels. One for diffuse, and the second one for lightmapping. My mesh has both uv channels defined but it seems the second one doesn't appear after the upload.
I tried the upload with multiple uv channels from 3ds max according to an old tutorial that seems to be obsolete.
Could someone give me a hint on how to set up multiple uv channels in max so that sketchfab understands them?
Thx in advance and happy holidays!
