More Stone

This mod pack introduces a substantial enhancement to the subterranean experience by injecting significantly more variation into the generation of both common stone and its deeper counterpart, deepslate. The primary goal is to increase the sense of natural randomness and geological complexity throughout the world's extensive cave systems, mineshafts, and underground biomes. Instead of uniform textures dominating massive areas, players will now encounter a subtle yet pervasive mix of different stone types, giving a more realistic and visually engaging feel to the bedrock layer and above.

What Mods or resource packs do I need for this?

you infact need none! Thanks to minecraft variation system with .json files. You are able to assign more textures to a single block! A good example of this is Simple Grass Flowers
