This is from something i do after work hours, mostly trying to learn things.
Naturally, i know specular maps can have colors, but i’ve come across some (i’ve dug them up from some games i bought, i hope that’s not a problem), which the color distribution makes little to no sense if you just apply them. Running one of them through GIMP (they’re .tga files, btw) shows all 3 channels make very distinct lighting patterns by themselves, so i could just separate them into 3 picture files and try using them like that, but i’m pretty sure i’d not be making the best use of it that way, and i’d probably be missing out on some important knowledge. I’ve tried using the node editor to isolate a specific color’s influence, but so far i’ve had no luck (i’m fairly inexperienced with it, since i’ve mostly been animating till now), and google hasn’t been kind to my searches, though i’m pretty sure i’m lacking the correct terms to begin with.
So my question is, is there a way to control a specular map’s behavior based on channel, or something to that effect?
Thanks for your time.
