Canvas with Just Eyes

DanaC78

When I render, i try to break apart pieces to postwork in Photoshop. I used Mask and Multipass Tool to get these different items. For eyes, it was done using the surfaces, and I can make adjustments to that without affecting the skin. However, I am not seeing a way to do this with canvases unless I am missing something.

No way that I can tell. I thought the material ID pass was supposed to be used to make say selecting the eyes in render easier, but it doesn't seem to work the way I would have expected.
