Does the attached composition work for anyone using OS X 10.7? Work, being defined as successfully applying the video texture to the GLSL Grid, via the glsl shader. This composition uses one video patch, connected to a GLSL Environment patch's texture input (using the default GLSL shader program), with a GLSL Grid patch inside of the GLSL Environment.
This works fine for me in OS X 10.5 and 10.6, but in 10.7, it looks like the vertex program is broken, possibly something to do with the gl_TexCoord. I get what looks like the average pixel value, or when an image is fed to something with improper UV values, across the GLSL grid, instead of the video image I would expect to get. Possibly related, when I make fragment shaders in OS X 10.7, things seem to work as expected, until I place them in a Render In Image Environment, at which time they sometimes flip on the Y axis. This is when using a 100% stock install, with no plugins or patches. -George Toledo
