thx!
I gave that a try, but don't exactly know how to set the alpha to 1. What if you want to use the alpha of the model for transparency, you could use the alpha of the normal map, eh?
My spec mask is much smaller than my color and normal map, does this save on memory as opposed to putting it in the alpha channel - I guess probably not as the alpha is only 8-bit.
Transparency seems to mess things up - I know of the plant 2-sided texture, and am trying to implement that in this shader. Any help on this?
