hi,
I am working on a customized painting tool that has some epecial treatment that i can get from 3dsMax viewport canvas tool (I tried to modify it but still can’t get there).
now I am trying to have the texturemap update itself as soon as user painting on it, so I need the most efficient way to copy the bitmap. Now I can’t find any way to do it except saving the bitmap, but saving a bitmap cost too much time to have ideal painting experience (basically it feels like painting with photoshop CS5 on a PC from 90’).
anyone has ideas? any input is appreciated 
thanks a lot!
