Re: Strange Issue with Expression Control Effects and Precomp

Thanks for the reply, but yes - ANY keyframes "break" the rotation.

The CC Sphere effect is in a precomp, with no keyframes. The Angle Control effect is in the main comp. I tie the Y Rotation of the Sphere effect to the Angle Control with a simple expression. When I manually drag the slider control with no keyframes set, the rotation works in the comp viewer. But as soon as i try to animate it with keyframes, it stops responding. The keyframes don't work, manually sliding doesn't work - it just breaks.

In my old project, I already had keyframes set for the angle control, and they used to work perfectly (I have old renders to prove it) but when I import the project now, the keyframes are still there, the expression is still linked properly, but nothing happens.
