Block Variants Mod (1.21.7, 1.20.1) – Missing Blocks in The Vanilla Game

The Block Variants Mod (1.21.7, 1.20.1) is a decorative expansion that fills in the gaps left by Minecraft’s default building block sets. While Minecraft offers many base materials, it often lacks complete variants such as slabs, stairs, fences, and walls for those materials. This mod changes that.

Designed for Forge and NeoForge, Block Variants introduces a wide range of new block types using textures and themes already familiar to vanilla players. Whether you’re a builder looking for aesthetic freedom or a survival player wanting more options for base design, this mod provides the extra pieces Minecraft forgot to include.

Features:

New Decorative Blocks from Vanilla Materials:
Adds stairs, slabs, fences, and walls for blocks that don’t normally have them in vanilla Minecraft such as Polished Diorite Walls, Amethyst Slabs, and more.
Expanded Crafting Recipes:
Allows players to craft traditionally restricted blocks from alternative materials. For example, you can now craft furnaces from granite instead of cobblestone.
Texture-Accurate Designs:
All new blocks are styled to match vanilla textures perfectly, making them feel like natural additions to the base game.
Survival-Friendly Integration:
All new block variants can be obtained through crafting and survival progression no creative-only access required.
Lightweight and Compatible:
The mod does not alter any existing game mechanics or items, making it safe for modpacks and world saves.

Why use Block Variants Mod?

If you’ve ever felt frustrated that your favorite building block doesn’t have matching stairs or walls, you’re not alone. Minecraft’s block variant coverage is inconsistent — some materials have full sets, others have none.

Block Variants Mod solves this elegantly by offering a wide library of new block forms crafted from materials like andesite, granite, amethyst, and more. Builders gain more flexibility, structures gain more coherence, and players get more value out of existing resources.

This mod is perfect for:

Survival base designers
Creative builders seeking material parity
Modpacks focused on aesthetics or architectural realism

It doesn’t bloat your mod list it just completes the block sets Minecraft started.
