I just started learning OpenGL in BMax today, and I'm having this problem. I'm loading my images with LoadPixmap() before shipping htem to the graphics card for a texture, and it seems that LoadPixmap() discards .png alpha. It loads it with the format PF_RGBA8888, but all of the alpha data is set to full. I used MaskPixmap() to create another pixmap with an alpha determined by a mask color. This shows up like it should, so my OpenGL part of everything is correct.
Anyway, was this issue ever resolved?
