Another faster way is to use shaders. Start with the first example in 10.GLSL. ++

Hi IOhannes,
Thanks for the quick response, I need to change some pixels gray values after an pix_data analisis. I might try to use a rectangle with a translateXYZ, or something like that.
Diego.

I mean, something like change de pixel x=310, y =200 to gray=0.5 > [pix_rectangle] could be used for that, if you are sure that you really want to modify the pixes (a faster way would be to place some properly sized geo on top of the texture, but of course this might not be exactly what you need) fgmkasdr IOhannes
