Thx! I found out about it a couple of hours later ;-)
Next problem I've got, is the following: I want the camera not to run through a sphere during following my target object, i.e. I want it to collide with the sphere. Is it possible to make the camera a rigid body in any way??
I tried to cover the cam with a rigid BoundingBox and parented cam and BBox, but that didn't work!
