Hi!
I'd like a 3D Null to get the orientation of 3D a layer. (without parenting, it would be too easy 
)
I've tried a lot of solutions, through orientation, rotations, both combined... some results are close, but never perfect.
If I'm right, orientation is computed before rotations...
I think the simplest way would be with auto-orientation, or the lookAt() expression on orientation, wich gives me correct X and Y orientations, and then get an expression on zRotation to get a "full" orientation.
But what would it be?
How can I get the Z orientation in layer space?
Any idea will be appreciated!
