without textures and lots of pix work this is fine - but I'm wanting to use plenty of movies and largish graphics as textures, which would be present from a different point of view in each of the windows. It would be better to only read from the drive once, then decode using the CPU a single time, and to only transfer one copy to the graphics card - so it seems either 2 windows in a single pd or a way to pass references to textures already loaded between 2 different pd's is what I'm looking for, but I'll fall back on one machine per projector if required. simon _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
