I'm having an issue with the external compositing tag in Cinema 4D.

Here's my scene setup:

I have a plane with an external compositing tag attached to it, this is set to rotate 360 degrees.

Extracting the cinema 4D data into After Effects produces the null as expected; however the keyframe rotation of the null is slightly off.

After looking at a few things I *think* it's because the interpolation in C4D is set to spline (changing the keyframes to linear in C4D aligns the null properly but obviously I lose the easing..)

Any ideas as to how I can pull in the interpolation properly?

First, please consider filing a bug [link].

To work around this, you can bake the object in C4D. In the timeline window, select the plane object, then use Functions > Bake objects...

Make sure the frame range covers your needs. Make sure that you choose "Create copy" so you can go back and edit the original later (and re-bake) if you want to. Make sure that Rotation is included.

You may want to turn off rendering for your copy in the object manager.

Hi Walter,

Thanks for the quick response! Unfortunately it also seems as though Cinema 4D lite doesn't support animation baking.

I'll submit a bug report, just thought I'd check first in case I was missing a step!
