Incorrect conversion from fbx to json

I ran into something similar with wheel rotations. In short, if there was more than 60 degrees of rotation per frame, the imported animation would show a reversed direction. My solution was to scale my keyframes in the original animation so that everything was slower and to then run the animation at a faster speed in PlayCanvas.

FBX Wheel Rotation Anomaly

I ran into this problem while working on a project that had train wheels rotated by an associated FBX animation. So I figured I’d share what I found out. The anomaly was that the wheels were rotating backwards. At first I thought that maybe it was a stroboscopic illusion, but that wasn’t the case. The wheels were really rotating backwards. The animation was super simple two keyframe change in pitch. After a series of experiments in a test project, I determined that if the pitch changed by m…
