I hate to reply to a threads so old, but this seems that it will have to be this way...
Because, I was trying to integrate krypton with flat red ball, but all of the transparencies in my glyphs are draw in black, instead of as a transparency.
I've already tried to debug the problem and it seems something related to either the final texture blending or the blur step. The game is open source, so if you want to see the code just ask.
Also, how did you make it to integrate krypton with flat red ball broknecho?
