I made a complicated nodes setup for a material using Cycles. Is there an easy simple way to peek at the data passing through any node, to view it as an image? I desire something like an oscilloscope, where I can touch a probe to any point of the circuit and see what kind of signal is there.
In Blender Internal, I could make many Output nodes and hook them up anywhere, and they'd show the data as a texture on a sphere, cube, Suzanne or whatever. There doesn't seem to be anything like this for Cycles nodes.
Example of using Output to monitor textures along the "circutry". (This is not any sensible texture; just messing around with BI nodes.)
