Surface Baking Catmull Clark SubD Model

[mezzi]

Does anyone know the best way to surface bake a catmull clark subD model ?

I am having a problem with UVs and surface baking when using catmull clark.

Firstly when I am in catmull clark mode, when I add UVs the UV window only displays points, not polys.

Secondly when I Try and surface bake the model in layout using Surface Bake Camera the UVs show as if they are not subD and are all square edged.

Any info or help would be great

Thanks!
