I'm trying to make a simple perlin-noise macro using the GLSL noise3() function, driven by fragment X/Y position. The shader works fine when rendering directly, but not when placed inside a Render In Image patch an connected to a Billboard (I get glitching along the left-hand edge of the output image).
I need to be able to pipe the result of the shader to other patches. Anyone any thoughts on what, if anything, I can do to fix this? I've attached the QTZ below. I'm on a 1st-generation MacBook Pro ATI X1600 256MB GPU MacOS 10.5.5 QuickTime 7.5.5 Cheers, a|x http://machinesdontcare.wordpress.com
