Hi, http://blenderartists.org/forum/archive/index.php/t-314216.html I`ve read that thread and I wanted to do my own php script for wrapping texture with using UV coordinate pass map. So, I did php script which takes color of current pixel from pixel calculated as red value multiplied by pixel X position and green value…
You'd need to give us some code to see what the issue is. We don't know how you're getting the screen space coordinates or how you're applying them. I'm not sure PHP is really designed for that kind if work, either.
