hmm, google did not help me... can you point me to some documentation about how to do this in OpenSG? then i have a semi-OT/related question: i'm also confused about the terms "multisample transparency" vs. "transparency supersampling"? is this the same? how do i enable this multisample transparency on linux (amd64, kernel 2.6.17, xorg 7.1, nvidia drivers 1.0.8774, quadro fx)? thanks, simon ------------------------------------------------------------------------- Take Surveys.
