hep cyrille thanks for this hint - though it's my first time using shader - i tweaked around a bit with the example. i changed color saturation towards muchocolore in the texture.frag file. although removing color to get a black & white image i'm also loosing opacity f.e. with color = color* 0.1; the image gets almost black. where aside the green behind my ears can i find infos about how to handle the shader? thanks&salutis olsen
