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.
Block Variants - Biomes O' Plenty, the long awaited expansion that extends the variety of Block Variants to Biomes O' Plenty.
Just like the original Block Variants, this expansion provides you with tons of new blocks that Biomes O' Plenty has been missing, like all the log stairs, slabs and walls, giving you even more creative freedom.
If there are any other block variants you need just let us know!
