Many MSG presets that generate 1 channel procedural textures use the 1to3GradMap processor to index map the black and white texture image through a color gradient to generate full color output. However, you can also work with 2 different color gradients to colorize procedural imagery. This post will show off how to do this using the 1to3ModGradMap processor.
The image gallery shows off the IO (input-output) connections for the simple MSG preset that generated the procedural image at the top of this post. Note that 2 different GenAdvTurb processors are used to generate 2 different turbulence noise fields in the ROut and GOut image channels.
