Hi,

I have a simple question: I must create some transparence in my texture.
I want to use the alphafunc to eliminate some pixels of my texture. I've tried:

        pfOverride(PFSTATE_ALPHAFUNC, PF_ON);
        pfGStateMode (gstate, PFSTATE_ALPHAFUNC, PFAF_GREATER);
        pfGStateVal (gstate, PFSTATE_ALPHAREF, 40.0/255.0);

        Or

        pfAlphaFunc(40.0/255.0, PFAF_GREATER);

But, it isn't work very well.

If you have some example, please, send me.

Thank you,
Soraia
