Re: Expression for Camera Z-Rotation

Hey Trent,
thank you for replying to my post! I just discovered that you posted so I hope you can still respond ...

Alright, I'm animating a camera flying over a google-like map while countries, borders and traveling routs of ancient kings and their armies and sorts of stuff blend in. So the flying camera should look kind of real too. Most of the time it does but other it doesn't: For example the camera travels around a spot in a circle. Untouching the Z-Rotation of the camera the entirely map rotates upsidedown in the cameras viewer. What doesn't look real at all (when I walk around a spot nothing turns upsidedown).

So far I adjusted that "misbehaviour" of the camera by the Z-Rotaion with a layer of circles that move in X and Y coordinates beneath the camera (if the circles fit symmetrically in the viewer the camera is stable - a good working brute force trick!).

But that way it's too tedious if you change the path or something of the camera. And it's not accurate at all in some situations.

So that was the reason I was wondering about a expression that turns the Z-Rotation in that way did it to make the animation look right.

Auto otrientation off make no use, parenting the camera to a null ether because other expressions aren't working anymore.

Trent, I hope I could make it mor clear now what my problem is. It would be more than greatful if there is a solution you might know of.

Ta,
Sebastian
