if i create say a "max" option (math function, such as add) is it possible to save it in the menu for shader parts? NOT save it to the library as a shader design, but to the menu with all the functions/patterns to choose from :) also, another question if i use a mixer, and put in 2 texture maps, then use formula to drive the mixer, is it possible to access the 2 inputs and get the colors of the pixels at a chosen area?
