See here for a tutorial on how to use the creator. (Or here for an image if you're not in the DG Discord.)
The creator looks different now, but functions exactly the same.
Please see this tutorial to use Custom Eyebrows. This will work on mobile as well.
(I apologize that there's no better option at this time. I'm seeking help on getting them to work in Creator's script.
If you're familiar with Javascript or anything adjacent/coding in general and/or interested in helping, please contact me on Discord.)
Current version: 2.4.13
