I love this tool a lot!
For my specific project, I have had some trouble sourcing characters & matching portraits while maintaining the same theme. Nonetheless, combining this tool and additional software has allowed me to maintain a consistent look for my characters while saving time!
For example, I needed a blue skin tone for a portrait that I liked, so I simply modified the editor to include additional tones and added new variations of the provided heads to get a repeatable version of my characters.
The same is true for slightly modified faces, armors and more.
Wonderful work, thank you for sharing this with the masses!
