So I’ve been having a lot of issues with exporting an insect that is rigged and animated, however when I export it as an FBX file, the left leg bones are flipped upside down and the animation gets misplaced somehow.
I have tried a few troubleshoots such as changing some export properties and making sure the bones are orianted properly and transforms are reset, but I have not found a solution yet.
Also When I import the FBX file I get error code in the info log. I can’t really read python but someone might know what it means:
Python: Traceback (most recent call last):

Here are the blender files if you want to look into them or troubleshoot them as well. Hopefully someone is able to help
