I'm having issues with my textures when I upload my scene to sketchfab. I use 3dsmax and the app from sketchfab, without lightbaking (when on, it's even more weirder + we aren't allowed to set this on according to the assignment) etc. Once uploaded, everything seems to be normal, all the models are displayed correctly without textures ofcourse. I just need to apply the texture, but then it doesn't show them correctly: they are either stretched or tiled. I presume it's an issue with the unwrap, but in my max file everything is like it should be. Then I tried to upload it via the website via a 7zip file containing my max file and all the textures in jpeg, but I got an error that one of the files is not supported (error 10).
The strange thing is that I can upload any model from the app correctly, but with my scene it's just not working. Any idea what I'm missing here?
