i need help pretty quick, for some reason my materials does not come with my model when i upload them to sketchfab. i cant seem to figure out how to either, it used to work before. ive uploaded previous models and its been working fine.

Are you exporting as .obj? If so, do you have “Write Materials” checked in your export options?

i opload the actual blendfile, that is what i did 10 months ago with another model, and i tried with that model this time, same blend file, but did not get the materials.
