This resource pack transforms standard Minecraft chests into volumetric 3D models that look significantly more realistic. For the modification to work, you need to have Optifine or a compatible mod loader installed.
The resource pack is compatible with almost any texture packs - it automatically adapts to the chest textures being used, creating three-dimensional models based on them. The only exception is texture packs that already contain their own 3D models or animated chests.
Please note: the dark color of the chest's bottom is not an error - it's a design feature that appears when using the standard Minecraft texture or textures containing similar color schemes.
