Before I try to make anything transparent, the model renders nicely. When I change the uv layout so that one piece of the model will be transparent, it renders horribly. This is the result with a translucent green texture:
I did transparency with OpenGL when I did 2D games and everything worked nicely because of these two lines:
glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
Now, I fear, this won't be enough, right? Or maybe I should use some other technique?
