Maya - Baking Normals From Material IDs

Zer0Naught

Hey guys, hopefully a quick one. I've not managed to find much about this for Maya, so here goes.

Simple version: I want to bake normals using material ID's instead of explode baking things all the time.

The link below starts with something like this: "bake from a high poly model to a low poly by matching material ids to avoid intersecting." I'm curious, is it possible to do in Maya?

Here's what I want to do:
> Assign different materials to different parts
> Use those materials as identifiers for baking
> Bake all ID's down onto a single map

Cheers.

I don't think Maya can ignore portions of a single model when baking, if that's a consideration. But if you have objects with the same material applied, you can use the hypergraph; right click a material and "select objects with material". Even if only a single face has that material, maya still gives you an object selection for that object in Transfer Maps.
