Every time I import this plane with bones on it as a custom rig, the Avatar Importer freezes up for about 5 seconds, imports the rigged mesh, and then makes studio run at 0.1 frame per second every time you open the place file. This is the only file that’s produced this behavior for me 100% of the time and it’s completely blocking any chance I have of using the Avatar Importer right now. Below is the minimized place file and the FBX.
