3D Versions at some point in the Future across all of your Variant mods? Or are they compatible with 3D Resource Packs/Mods? Either way it'd be super cool to have 3D Versions.

Seems easy enough to do, although somewhat long winded.
May do it as an optional texture pack.

If there is any way I can possibly help you, let me know. Not sure what program you use to do texturing but I am more than willing to try and help if wanted. It looks really good!

You'd have to show me an example because im not sure what you mean.

This is from the Vanilla Tweaks Resource pack.

Hmm, interesting.
Looks much better, will take a look at this.
