Hi, sketchfab seems to be totally broken. Most models make it fail. STL files seems to work, but without textures. I also got some export using OBJ, MTL files, but textures don't show up.
I could upload the BLEND files that I downloaded for this exercise without changes. If I only open the file and save it as is then Sketchfab refuses that file with Error 13 (Invalid file content). This could be a version problem.
I think the exercises should change to upload images or movies. What do you think?
Hey ddadim,
I have checked this is issue, and I too got an error on the preview of the upload page, however when clicking view model on the top right, the model is fine. If you then click back on your browser you can return to the upload screen and the ax is visible in the preview and continue editing the upload.
I deleted the upload and tried again with the same model and it worked without an error the second time.
I don't know why this is happening but it seems to be a Sketchfab issue.
They must be reapplied manually in the sketchfab editor.
This is true for exporting to most other 3d apps btw, since even if the textures are included with the export data the other app may not know how to apply those textures since the material systems can be very different. Glad it's working for you now!
