Sizechange officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 26.1.2, 26.1.1, 26.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Sizechange – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Sizechange consumes the most tick time.
