Lightness
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.
V5.0.0 ALPHA AND ABOVE REQUIRE GECKOLIB
Lightness is a mod adding lots of new items about lightness! It includes a new ore, a new item from that ore, a new block from those items, much more new items and a new tool! However, you can still play Minecraft and your other mods normally - Lightness does not effect those.
