Is there a way to add texture to the game via resource packs
I mean that i want to have a separate texture for droppers and furnaces rather than have the same one for the both of them
I tried but failed
Also even though I'm pretty sure that this is not possible is there a way to have a items texture changed when renamed to a particular name just
You need to modify the block model to accomplish this. I think that This is the correct tutorial to link you to. If not, try This One.
I hope that helps.
