Permit me to be a heretic . . . for the moment, anyway.
A rail simulator player, I make my own content, trees and bushes, included. Using gmax and the associated gamepack, I was able to make those things in one two ways.
I would create an Alpha channel in the art program, such as Paint Shop Pro, adding it to gmax, to make the tree or bush.
I would also, sometimes, create a white mask, using that in gmax to create the same effect.
Thus far, in Blender, I can create those objects by using the Alpha channel, generated in Paint Shop Pro.
However, I have, thus far, been unable to find a way of using a bitmap mask to do the same thing.
Am I able to use a bitmap mask in Blender? If so, how do I go about?
Any help will be greatly appreciated.
Thanks in advance,
