Procedural Texture Saturation Mask (Part 6): Creating a Macro

Summary

A variable saturation mask can be a very useful tool. Here we take the final step in taking the Procedural Texture mask created in the previous video and saving it as a simple macro. Note that we will be going very slowly with this, explaining the detail of how macros work.

The formulae to use are:

R:
(d*(1-((max(R,G,B)-min(R,G,B))*(a+1)*(b+1)+c))+(1-d)*(((max(R,G,B)-min(R,G,B))*(a+1)*(b+1)+c)))*(1-e)+e*R

G:
(d*(1-((max(R,G,B)-min(R,G,B))*(a+1)*(b+1)+c))+(1-d)*(((max(R,G,B)-min(R,G,B))*(a+1)*(b+1)+c)))*(1-e)+e*G

B:
(d*(1-((max(R,G,B)-min(R,G,B))*(a+1)*(b+1)+c))+(1-d)*(((max(R,G,B)-min(R,G,B))*(a+1)*(b+1)+c)))*(1-e)+e*B

A:
(d*(1-((max(R,G,B)-min(R,G,B))*(a+1)*(b+1)+c))+(1-d)*(((max(R,G,B)-min(R,G,B))*(a+1)*(b+1)+c)))*e+(1-e)*A

For this to work, you need the following sliders and controls below (all initially defaulting to zero):

-1,1: a: Stretch/Squeeze

Z: b: Stretch Boost

-1,1: c: Shift

Z: d: Invert (0=Sat, 1=Desat)

Z: e: 0=Preview, 1=Mask

The pre-recorded macro for this can be downloaded from the saturation mask set of macros here: Dave's Saturation Masks (Procedural Texture only)
