The real Steve & Alex Minecraft models live in The Sims 4, plus Minecraft blocks in Build Mode, all from your own Minecraft.
Minecraft moves into The Sims 4.
MineSims reads the Steve and Alex skins and the real block textures from your own Minecraft: Java Edition and turns them into Sims 4 content on your PC. Nothing from either game is shipped.
What you get
How it works On first Play, Melty runs MineSims' setup. It finds your Minecraft jar (from the official launcher, Prism, Modrinth or CurseForge) and your Sims 4 install, then builds everything into your Sims 4 Mods folder and switches on custom content and script mods. It takes about 30 seconds.
Needs: The Sims 4 (base game) and Minecraft: Java Edition 1.13 or newer, started at least once so its game files are on your PC. Single player.
Cheats (Ctrl+Shift+C): minesims.dress steve / minesims.dress alex turns the active Sim into Steve or Alex; minesims.household creates another Steve & Alex household.
