Transparent textures

[Bart]

Hi,

I have a question about the trees in http://www.gtatools.com/tss/ (mentioned in "Your projects"). The leafs are transparent textures without having Z-buffer problems. I don't think the leafs are sorted from back to front as some leafs intersect. Wich techniques are used for the trees?

simple alpha testing

gl_alpha_test ed geometry doesn't need to be sorted before rendered
