I've been searching for an answer to my question, but my Google-Fu isn't quite up to scratch to figure out what is likely a pretty simple question.
Anyways, I'm looking to improve my hair on my character models in Blender Internal. I am looking to use alpha maps to make hair strands appear nicer and rounder while conserving on polygons (as I'm trying to eventually do models for games and animations in a cartoony-stylistic approach, a low poly count is vital to me).
I was wondering if anyone knew how to have a colour map and an alpha map work together. For example; I want one map where all my strands are on top of eachother on a texture like this:
Where he has all of his locks of hair on the same spot of the texture so that all the strands go with the grain.
And then I also want a separate map like this:
Where I can control the alpha of each individual hair.
How can I do this?
