I was trying to upload some FBX animation files today and one of the character's bones always seems to go crazy, disconnected and scaled up. I thought it could be Maya exporting problem, but I uploaded an old FBX file that I know worked before, and it did the same thing.
Anyone else experience this issue? Is it Sketchfab problem?
