Hi everyone,

I'm struggling with a project right now and can't seem to find the appropriate orientation / rotation expression.

In this project I have 3 layers, the floor, the ladder and the guy.

I have to keep the guy perpendicular to the floor. But the guy layer is parented to the ladder, and the ladder is animated on all it's rotation axis (imagine a flying carpet, but looking like a ladder).

I can't seem to find the correct expressions to keep the guy perpendicular to the floor (which can also be animated on it's orientation/rotation axis) in all cases. The guy parenting to the ladder adds a lot of complication that my non-math-friendly head can't seem to overcome.

Any hint ?

Cheers,

Seb
