Just 3D

Just 3D is a pretty lightweight resource pack that is simple to use and built from the ground up, and only adds 3D models to the game!
Unlike a few texture/resource packs, this adds no new panoramas or splashes to the game, and only makes some models 3D, and doesn't overhaul the models completely, to make it feel more vanilla.

This pack has also been tested and it has been confirmed that the pack is well-optimized(by adding backface culling when needed, and more), with little to no impact on performance, and has actually increased it sometimes!(See the gallery for more info)
This pack is still in beta, so a few things may break, though probably not.
One of the best parts of this pack is that it works with almost any resource pack, as long as they only change textures or very basic models, just make sure you put this resource pack over the top or some textures may break. (about 90 - 95% compatible with other resource packs)
This pack has taken me a while to make, so I hope you enjoy.
If you notice any pixels out of place, try pressing F3 + T to refresh the pack, it happens sometimes. If it doesn't go away, report it to me.

Note: Faithful 64x was used as an example for some screenshots, you can get it here.
