Merging masks together



SUMMARY

​Goal

      • Main goal is to keep script readable without having to open every single node to fish for information

      • This will also help with better flexibility and performance

      • As you're just starting out, prioritize script layout first, then image quality

      • There is no good excuse for a messy script

​Merging

      • Since we're only merging masks in individual channels, prefer the ChannelMerge node to the regular Merge

      • ChannelMerge has a distinctive shape which makes it easy to identify, and merges only 1 channel at a time

      • Merge should be reserved for blending whole layers instead (aka color and alpha together, RGBA)

      • Most important operations of the ChannelMerge node are union (combine together), stencil ( A punches a hole in B) and in (B is limited inside A, and vice-versa)

      • For cases where you need to replace entirely instead of blending, good simple option for now is the KeyMix node
