IMPORTANT NOTICE: As of release 2.0.0 for Minecraft 1.14.4, Unity has become modular. Support for vanilla Minecraft will be separate from mod support, texture maps for shaders, and random entities/ctm for Optifine. Unity: Modded can be downloaded here. Unity: Texture Maps can be downloaded here. Random entities and CTM will be available at a later date.

The Unity resource pack follows the traditional Minecraft aesthetics but adds subtle depth and more natural colors. Mods are retextured using the Unity pack for vanilla Minecraft as a base and will have unique design characteristics tied in to stay true to the original. The idea is to keep the authors original vision alive and well... but packaged a little nicer.
Vanilla Minecraft was retextured simply because I felt it was falling behind, visually, compared to the look of mods these days. The scope of this project is to set a common ground; touch up vanilla, unify mod textures, and keep the mods unique.
