Do the CoordinateSystem LOP + MtlxPosition/TransformPoint workflows support spherical projections? I've tried various combinations of MtlxPosition/TransformPoint and I do get some results (simple results like camera projections are pretty straightforward... the docs are clear on these setups). But I'm struggling to get a world-space spherical projection from the coordsys prim's position to work.

Any insight is much appreciated.
