I am sorry if this question has been asked before.
I have my json file with my cubik studio generated item :

It's on models/item/arrow.json
There is also a textures/block folder, I already try to put texture that cubik studio give me but it didnt work, so I dont know where to put my png texture file at so I dont have the violet and pink base texture on my minecraft new item ^^
Thank you !

+ is it possible to use basic minecraft texture ? That actually what I want to do so if you can tell me how to do both
