Overview

◬ Penumbra is a work-in-progress resource pack created by RetroAdvance64. The pack focuses heavily into transforming the world of Minecraft under Retro's vision, looking more grunge, gritty and almost darkened.

Keep in mind that this project for the time being is unfinished, featuring a good chunk of blocks and items resprited and meant to be seen with the current blocks generated in a vanilla world-gen.

It is highly recommended to use Penumbra with Optifine / Entity Texture Features & Entity Model Features to active special features such as Stray's glowing eyes, custom Wither model, etc.
