Anyone know how to export UV snapshot of simple Maya scene?

Trying to take a simple UV snapshot within Maya in order to create a texture atlas for these simple objects (a few cubes and slopes)

Every attempt I’ve made has failed… Anyone know how to do it? :face_with_spiral_eyes:

open the UV Texture Editor, in the editor menu chose Polygons–UV Snapshot…

Ah… is it really that simple? Thanks!
