I was commissioned to make an avatar using this program & so far it's been super easy to use! But is there a good way to send it to them without them having to tweak all the settings &  everything or will I need to just send them the images & just walk them through setting it up?

I'm not sure, honestly.  I ended up having to do the latter... send them all the images and screen shared the program showing how to set them up.

I think if you send them the whole folder of the character (that contains the 'images' subfolder and 'character.json' file) and have the recipient place it in their own 'characters' folder it should appear in the dropdown when they (re-)open Honk
