About this Mod

Polymorph Continuation

Polymorph Continuation is an unofficial community port of Illusive Soulworks' Polymorph for Minecraft 1.21.11 on NeoForge.

Polymorph solves recipe conflicts by letting players choose between all valid outputs that share the same ingredients. This beta continuation build keeps that behavior available for newer NeoForge environments while preserving attribution and the original LGPL licensing.

Frequently Asked Questions

Polymorph Continuation server crashes on startup – what to do?

Most common cause: wrong neoforge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.

Is Polymorph Continuation compatible with neoforge?

Polymorph Continuation officially supports neoforge for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Polymorph Continuation – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Polymorph Continuation consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
