What files were you working with and what animations were effected?

[jdperos]

In this example, it's "Nml_Wait" from Breath of the Wild's Player_Animations.bfres. It happens in a variety of BotW files, seemingly at random frames as far as I can tell. It seems that it's generally the waist bone's rotation that's affected.

Of note - the animations look fine in Smash Forge's viewport. But exporting the SMD and viewing it in either Noesis or 3DS Max gives these Gimbal locks and noise.

You can upload files on github issues.

Is there still necessary information that I can help provide?
