For some reason my Sun Witch model has a streched bar sticking out from her back. In blender there are no problems. I have applied all transforms and checked for geometry issues. I Checked for weight paint problems or armetrure problems and also tried uploading with .blend , .DAE , .STL and .FBX. This problem keep happening.
I have a feeling that the problem is from SketchFabs side.
How do I fix this?
