Grass Rocks+ is a texture pack that adds little rocks and pebbles to grass and related blocks! This even works in the Nether, adding little netherrack stones on warped and crimson nylium!
Features:

• Well-optimized — This pack hides invisible faces and uses culling to ensure the rocks have little to no performance impact!
• Compatible with other packs — This pack dynamically adjusts the texture of the rocks to fit with the resource pack you are using!
• Clean and random — Grass Rocks+ has different variants of rocks with different rotations, and has been engineered to make sure they don't clutter up you world.
• Vanilla-friendly — This pack works completely in Vanilla Minecraft with no compromises whatsoever! !Grass Rocks in a Plains Biome
