I went looking to try to add custom textures to Doggy Talents, but I couldn't find any file that refers to the textures. I also tried looking for tutorials, but didn't find any videos for 1.12, nor did I find anything on wiki pages or other forums. I have no idea how adding new textures works, and I would like some help on that...

Add new textures to a resource pack as so:

textures 0-14 are already in use (you can override them if you want) so use index 15-127

Okay, how do I set that up?

I haven't tried adding it as a resource pack, but the file should look something like this, right? Please reply with an answer; I can barely wait any longer to try making textures, but I'm also deathly afraid of breaking Minecraft because I got something wrong. -_-'

Yes that looks fine, copy and paste that "DoggyTalents Texture WIP" folder into the resource packs folder. Fyi you won't be able to break minecraft

I have it figured out now. Thanks for the guidance! <3
