This pack modifies every single texture (except the vignette and panoramas) to only use colors from an 8-bit color pallet. That is about all that was changed. It is a large pack but simple. Just like the textures themselves.
This pack looks very good in structures, especially the ancient cities and the trial chambers. It makes it seem like you are playing not in Minecraft but like you are back in the dungeons of The Legend Of Zelda and other amazing games from that time. This pack is especially good as well for player built structures as the refined materials look really great.
If you would like to be able to use Fresh Animations at the same time download the compatibility pack here.
-The images in the gallery were taken on the Hermitcraft 9 map so I could show the textures used in something a player made.
