I get issues almost every time I upload. I was uploading as .fbx to avoid this, but that isn’t enough in every situation, as you can see here:
The crotch has significant vertex abnormalities.
How are you all getting along going from Blender->Sketchfab? I typically use automatic weights first, and then modify from there. Is there a way to use Blender that is friendly to Sketchfab? I can obviously go in and meticulously modify and reupload over and over until it’s good, but that is far from ideal and a major time sink; not to mention it probably hurts Sketchfab’s servers
I’m aware of this thread: Weight painting translation from Blender 2.8
But, like I said, I tried .fbx and it doesn’t always work. There aren’t any other replies in there either.
