R3D is basically an extremely HD version of the default texture pack.
R3D.CRAFT, pronounced “Red Craft” or “R-3-D Craft”, is a high quality texture pack that can be applied to the game, Minecraft. Based on the default texture that belongs to this game, R3D.CRAFT tries to bring more realization, with high quality textures, smoother gradients and shadows, artificial lighting, small details or new details + so much more.
This texture is made for those who seek more quality in-game, but also want to keep the default design and feeling. Therefore, this texture tries to stay close to the original outlook, by matching the correct colors and shapes.
