When I saw the link sometime ago in the shoutbox to a video of creating fractals with visual feedback using projectors it seemed like a too easy to implement method to not patch it in vvvv. It all worked fine but when I tried to change the texture address mode I noticed it was always in CLAMP mode regardless of if I tried changing it with the Address node or in an effect. The different address modes normally work on my computer but not with this feedback loop.
My gfx card is ATI Mobility Radeon X700 if it might be of any importance.
