I loaded an rthro bundle into the game using a wear bundle plugin (which works off of BuildRigFromAttachments (or perhaps ReplaceBodyPartR15) and bundle API so I would assume the joints and etc should be correct) in order to make animations for a project, however it keeps giving me these terrible rotations on my character:
what I expected to get was:
This does, however, seem to work with a copy of the original character as a StarterCharacter
The point of this project is to work with all R15 and rthro rigs so this bug is annoyingly aggravating.
Afaik this happened when I was animating using IK but it should most likely happen in FK animations also (i disabled IK before exporting). I tried uploading the animation again multiple times (and there are no conflicting animations) and I also tried remaking it to no avail. I played the animation using the Play method from the API to test in the first and last recordings.
