Thanks! My other mistake was using DECAL instead of REPLACE in my TexEnv. I didn't realize DECAL was keeping the point's original alpha, which made the entire point sprite transparent, not just the X.
I still don't quite have the visual effect I want yet. When the X's are close enough to overlap, the topmost ones appear to be cutting a gap or casting a shadow on the X's beneath, even though alpha is 0 for every black texel (see attachment ps.jpg). I'd like to just have the white overlap (as in attachment at.jpg, from my AutoTransform implementation). Is there anything I can do to fix it? ... Thank you!
