Yesterday I've been inspired by Xisumavoid's VanillaTweaks resource pack feature to add textures based on item damage values. I finished all diamond tools and I'm probably going to do that with other tools later today.
I need some feedback, does it look good? Should I keep doing this? Should I make the files public?
Edit: I'm not the best artist in the world but you probably get the idea of what I was trying to do.

Looks very cool! I just noticed one inconsistency: The axe is the only tool where the gem at the handle gets destroyed. It looks kinda silly without it IMO.

I dig it. =)

It looks very good nice job. Why not upload the files. I might file a PR against you if the textures look good

I still like this idea. 🙂 If you ever get around to submitting a PR, I will happily accept.
