Hello,
I'm working on porting Andrew Benson's optical flow glsl shaders over to PD. I've got the primary shader working, but need to send the output to the second shader. I figured that the best way to deal with this would be to use [gemframebuffer] to send the results of my first chain (including [pix_video] and the first shader) to a second chain to be processed with the second shader.
My first problem is that I cannot seem to get [gemframebuffer] to work with [pix_video] or with [pix_film] for that matter. Is this the appropriate tool?
Alternately, if someone knows how to use multiple shaders in the same render chain then I wouldn't have to use [gemframebuffer] at all.
