This is pretty much my complete AIO Flow. Has the capability of 4 char regional prompting + Background, IPAdapter, OpenPose, DepthMask controlnet, Remove Background, WD14 Tagger, Regular genning, detailers out the wazoo.

This flow uses custom modded nodepacks (Not by me (Links are in the txt document)).
Included some Gemini created Wildcards to get your started.
Prompt box area is structured so you can put a wildcard in any of the prompt boxes and have it processed by a wildcard processor.
