Before you posted this, however, I spent most of my time today trying to figure this thing out. I got it to work, eventually, but I set both the .ofs to zero and it worked, even though that is not the top left corner of the area. But it works. -- don't know about that > Off-screen drawing very useful for dynamic textures, mirroring, and > other > nice things After I got it to work, I wanted to try using chrome mapping with it. The only problem I'm having now is texturing an object for chrome mapping. Do you know how the texturing in the SCEE chrome demo was done? -- I cannot remember; but the source is definitely available from the SCEE website (chrome will be in the demos or samples sections), and is reasonably clear.
