Y Axis output for RotateAboutWorldAxis_cheap material node appears to be broken

I’ve tried with very simple material setups, the X and Z axis outputs work as expected, but the Y Axis output has inverted normals and needs a .25 offset added before the “rotation amount input” to get it to behave a bit closer to the other outputs. I tried searching for other people trying to use this node, but haven’t found any other threads, discussions or demos of the node being used.

Documentation is very sparse.

Can you show the material?

Here’s a simplified version. One cone for each output, X Y and Z. X and Z and behaving as expected and don’t have inverted normals.

Yeah, very weird. All kinds of inside out shading also.

You might be better off with the other node
