Good Afternoon,

Here is a shot I took of the interface, in Maya, where I spent about 3 hours straight on Wednesday. Now I would guess that many of my readers are not well versed in nodal work flows so I shall attempt an explanation.

Nodes can be thought of as a container with many compartments into which we dump a mixture, an image in this case, which is separated into its respective colors. We also have other containers sorting out things like gloss, thickness, transparency, and brightness. These containers are then connected with pipes, the lines with arrows, from the different out-ports to their respective in-ports on other containers which act as filters to decide how the pigment is to be used. Finally, everything is piped into a “mixer” which blends all of the pigments, based on a “recipe”, and combines them to make the final “paint” that is put onto the 3D model. The challenging part is making sure the right pipe is connected to the right outlet at the right flow amount. Just as in the example of paint, it is quite easy to have back flow, over flow, pressure points, and missing connections, in other words, a mess!

I hope that was at least somewhat helpful.
