Make The Camera Focus On A Rotating Cube On A Path In A Loop Animation How Do I Make The Camera Focus On A Rotating Cube On A Path In A Loop Animation ?

With Camera Constraints, The Camera Fails To Focus On the cube &amp; Gets Lost As It Moves Along The Path. With Camera Parented to the cube, I Can make the camera focus on the cube but I can't rotate the cube (When I rotate the cube, the background rotates but not the cube!

The Basic Idea is to have an animation where the cube rotates &amp; moves along a path while the environment in the background changes through out the Loop Animation.

I hope the question is not too large!
Thank you!

Never animate any object without a controler. 

In your case I would give a hierarchy that goes this way : A locator called MainCtrl => A locator called RotCtrl=> The Cube. 
MainCtrl would be the one constrained to the path and RotCtrl the one that would rotate the cube. The Cam could be the child of the MainCtrl. 
Then the camera could also have a Target (made with another locator) so that you could control how it looks to your cube during animation...

Whatever, NEVER animate directly your mesh, always use a control (rig) so you'll be able to change any geometry afterward without loosing animation
