That would work if the rotation would be one value,
but it’s 2 different ones for each object in the hierarchy.
With Look At Rotation on both of them, I get this:
Base is this axis:
And LightMoveManual is this one:
Base rotates on one axis 360 and LightMoveManual also rotates on only one axis.
Not sure how to combine two “look at rotation” in this case
Lost haha
