I have a c4d project with an animated Null object and export it to AE. Manual keyframes are exported. And this works in AE. If I have in C4D the Null animated with align to spline this results in AE with no keyframe is exported. So I think i need to bake all keys out of the align to spline procedure. Is this possible? I tried already with cappuccino but did not get the keys.
Select your object in the timeline, or drag it in there if it isn't in there already. With the object selected in the timeline, select Functions>Bake Object. Make sure Expressions is checked and click OK. That should do it.
