Hello! I have created a "camera and aim" where the aim is in the center of a sphere, I just would like to creata an animation where the camera is rotating aroud the sphere. When I select the camera I set a keyframe on the first frame, then I move forward on the timeline, I rotate the camera around the sphere and I set another keyframe, but the camera doesn't move through the timeline, why? If I do it with a normal camera (without aim) it works. Can you help me? thank you! :)

Hi.
I think the easiest way to do this would be...

1) Position your sphere at (0,0,0).
2) Create a camera (without aim) and move it away from the sphere in x or z.
3) Create an empty group at (0,0,0).
4) Parent the camera to your empty group.
5) Rotate your group in y.

This should work okay, I guess if the sphere is moving you could constrain the group to the sphere.

To use a camera with an aim, Im sure you could just parent the aim under the sphere, or constrain the aim to the sphere. I think the problem could have been that if you were keying the rotation values of the camera then the cameras rotation would have been thrown off because the cameras rotation should have only been driven by the aim vector.

I hope that made sense :)
