Rotating Polygon Generator in 3D Space

Hey all,

I’m currently working with a Polygon generator as an alpha mask for an image plane. Most everything works fine aside from the rotation of the mask… I’m not sure what it’s rotating around. Rotation Heading & Pitch both don’t seem to rotate around the origin. Rotation Bank rotates normally. Is there any way to get an effect of the mask looking like it’s rotating properly in 3D space?

I’ve tried attaching the polygon as a child of a null node and trying to rotate the null, but that has no effect.

Any ideas appreciated, along with any explanation of how the rotation works in the polygon node if possible! Thanks a lot :slight_smile:
