I am doing this experiment with Compositor Nodes and Cycles Nodes. There are times where I want to blur an image from Cycles and to bring it into Compositor, simply blur it and back to Cycles.
I have a feeling that this is not possible. But maybe there is a trick to be able to do this in a way that even though it is not realtime, it can be triggered and bake as needed?
A simpler test is if I am using Compositor, load an image, blur it or make adjustment and then export it into Viewer Node, is there in anyway I could ready that "Viewer Node" image into Cycles? --> I tried this does not quite work, I am getting pink color.
