Copper-Free Trial Chambers

by Trixtail

Copper-Free Trial Chambers changes how Trial Chambers are built, swapping out the large amount of copper blocks used in their design.

FabricNeoForgeServer-side onlyGNU Lesser General Public License v3.0 or laterOpen source1.21 – 1.21.1

What it does

Trial Chambers generated by the mod are built with a reduced share of copper blocks, which changes their look in newly generated worlds. The changes are backported from the 1.21.2 Trial Chamber design to Minecraft 1.21, so the same structure style is available on the 1.21 and 1.21.1 builds. The mod is open source under the GNU Lesser General Public License v3.0 or later, and it runs on servers alone, so players join without installing it.

Files exist for Fabric and NeoForge, with 1.0.0 for 1.21.1 on Fabric and 1.0.1 for 1.21.1 on NeoForge as the latest builds. Players may find it incompatible with other mods that change Trial Chamber generation, so server owners should test those combinations.

Key features

  1. Reduced copper in chambers

    Trial Chambers no longer use the heavy amount of copper blocks in their design, so the generated structures look different.

  2. Copper-light structure layout

    Generated chambers swap copper-heavy sections for other materials, keeping the same room arrangement and layout.

  3. Compatibility with generation mods

    Other mods that alter Trial Chamber generation may conflict with this change, so combined setups need testing.

Changes the design of Trial Chambers to not utilise an absurd amount of copper blocks. Also backports the 1.21.2 trial chamber changes to 1.21!
