Ow, I didn’t see the rest of your last post, I only saw the link before.
The only relevant to the spellbook function in the UI controller is the “Get Spell”. Is it firing properly?
The correct way to use your own controller is to make the UI controller a parent to your own. (then you can just use your own and everything should work…). Are you doing it like this?
Yeah, send a screenshot to the controller if you want, it might help!
