I am so confuse with XSI's alpha channal. Is white meaning show? or black meaning show? Anyways, this is not my main problem. let's say, I am creating a dice. I have 2 pieces of texture. One is for the entire dice using white. Another texture is for the dots on the dice. I want to put 2 texture to it to make a blend. The dot texture, i put an alpha channel with it, all the dots are in white, and the miror area which i dont' want to show, i put it in black. 2 texture are set. And how do i put it in XSI so that the dot texture is sitting on top of the white texture and do a nice blend using my alpha channel.
