I am trying to bring in a camera from a Blender 4.2 project to After Effects 2024. When I bring it into AE, the animation is wildly off. Where it should be rotating maybe 10-30 degrees it is actually rotating upwards of 180. I am using a Follow Paths constraint and have tried baking the animation. This does not fix the problem. I have looked at numerous other work arounds and cannot fix this issue.

I am working on a Mac M1 Studio. I am including the original animation file, before I started changing all the settings to attempt to fix the problem.

Hi, thanks for the report. I can confirm the issue, but cannot investigate it further right now. I’ll get back to you once I have access to an After Effects license.

So I could investigate the issue and it turns out the way you animated the camera is not supported by After Effects. Specifically, the curve you used as target to the camera’s Follow Path constraint has a negative scale (-9.333 on each axis). When the animation is baked, the camera’s scale is also negative, which cannot be applied in After Effects.

You can verify this by applying the camera’s constraint on any given frame (× button next to the constraint Influence). You should see that the camera does not move at all, but its scale is now negative (-1, -1, -1).

My advice would be to apply the scale on the curve so it’s positive again.
