Description

Session attached with named views v1, v2, v3 and soft lighting.

If I just use "view" to go gradually from one to the other, the lighting remains correct:

view v1
view v2 frames 120

However, if I use "fly" to go between these named views, the lighting is weird:

fly v1 120 v2

Fixed.

The fly command interpolated rotation positions as quaternions and then didn't normalized the interpolated quaternion, leading to the wrong motion and wrong lighting. Alarming that no one notice the horrible behavior since I added the fly command in 2021. It was producing non-sensical curved path motions.
