Hey guys,

I'm a fairly new to Cinema 4D and I'm struggling with key framing the rotation of an object. I can rotate the object (pink cylinder in the picture) just fine, but when I want to keyframe the rotation, Cinema 4D records the rotation in the world axis:)

and not the rotation of the object axis: ).

The aim is to rotate the object around the green axis.
Thank you and have a nice weekend!

What you've got there is a rotation order problem, which is a bit hard to to explain (check the help docs). You can fix it by deleting your rotation track, going to the object's coords tab, and freezing the rotation transformation. That will set the local coordinates to zero and you can now keyframe the heading rotation without any issues.

Another way around it is to use a primitive with Z orientation instead of Y orientation. You can always keframe Z rotation because it's first in the default rotation order. That's why bones and joints always have the Z axis running along their length.
