Block Variants
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Requires Ametrin API!
Block Variants provides you tons of blocks that are missing in vanilla like Polished Diorite Walls and Amethyst Slabs.
It also offers alternate ways craft things e.g. Furnances from Granite (use Just Enough Items to find out more).
Missing something? Let me know via discord or in the comments!
