Anything I need to deal with normlas…

 

The  base is an offset of sine or cosine multiplied by a channel r, g or b.

 

Example rotation on x axis (red channel of normals pass):

red is the pivot of rotation so stay the same: r

green : (cosR*g)+(-sinR*b)

blue: (sinR*g)+(cosR*b)

The same expressions are repeated having  green and blue channels of the normals passes as vixed axis. At the end you will have 3 knobs, x (rotating around red/x axis), y (rotating around green/y axis), and z (rotating around blue/z axis).

Variables

sinR = sin(radians(rotation_knoob))

cosR =cos(radians(rotation_knoob))

Just a sine/cosine converted in radians multiplied by a custom knob for rotations.

 

 

In the animation tab, there are some animation presets made by expressions:
