On this helmet at this point, how many different pieces are there to customize?

Fifteen.

So this helmet has 15 customizable pieces.

Fifteen submaterials. That's what each one of these are. We also obviously use glass. If I had the glass in there, that's not something we'd use layer blend for. It'd be the actual glass material. This helmet doesn't actually have glass; this one does. So we use a glass material as well. And then we also use an Illum sometimes, because then we can do glowy stuff like this. So Illum is a specific shader. In terms of setting up glows, we can do it now through layer blend or we can do it through an Illum. The advantage with the layer blend glow is you get to do really fun stuff because it's texture based.
