Is it possible to LoopOut("cycle") if the layer already has an expression? How?
As the title asks. I am animating a character riding a bike, and everything is driven by the pedal. As the pedal rotates about it’s axle, it has an expression inverting it’s rotation relative to it’s parent so it stays straight up. On top of that expression, there’s a few small adjustment keyframes so the character’s foot doesn’t stick out of their pants in strange ways. So, I need to loop the minor adjustment keyframes whilst keeping the pedal inverted to the root. Simply adding “LoopOut(“cycle”) to the beginning or end of the expression doesn’t seem to work, it is either ignored completely or overridden by the other expression.
r = transform.rotation + (thisComp.layer(“Pedal Root”).transform.rotation * -1);

I think you could just use loopOut() on the ‘pedal root’ layer’s rotation… since your expression is looking at that layer’s rotation it should work.

sorry, there would still be an issue with the layer’s rotation… we can still make it work, let me take a look.

Assuming that the key framed animation on the foot layer’s rotation loops, this should do it:
r = transform.rotation.valueAtTime(time % key(numKeys).time) + (thisComp.layer("Pedal Root").transform.rotation * -1);

Huh, interesting way to get that to work. I mean, it makes sense!
I guess the loopOut expressions just don’t play well with others?

The loopOut() and loopIn() functions only look at key frame data, neither look at expression data, so you kind of have to roll your own loop function to work with the rest of the expression.
