Hero's Anchor Optimizer
by herobane
Hero's Anchor Optimizer changes how respawn anchor explosions are rendered on the client, and it is a Fabric mod for 1.20 – 1.21.11.
What it does
The mod targets respawn anchor explosions and reduces the visual cost of them on the player's own machine. Its files are published for Fabric only, across 19 release versions, 1.20 – 1.21.11, and the latest Fabric file is 1.1.4-1.21.2-1.21.4 for 1.21.4, dated 2026-04-24.
Hero's Anchor Optimizer runs on the client alone, so a server does not need to install it. Fabric API is needed for builds up to 1.21.10, while the 1.21.11 build does not list it. The mod is released under the MIT License and is open source, and its source code is public.
The author words describe a set of alternative textures and a fake anchor model that can be swapped through a resource pack. Files for the fake anchor live under assets/herosanchoroptimizer/models/block, and the side and vertical textures can be changed one at a time. Any other mod that leaves the anchor's functionality alone should be compatible.

Use cases
Player-side performance
A player who sees heavy lag from anchor explosions can install the mod alone, with no server changes.
Custom anchor appearance
A resource pack author can swap the fake anchor model or its textures to restyle the block.
Who it’s for: The mod suits players on Fabric who play on PvP servers where respawn anchor explosions are common, and resource pack makers who want a different anchor look.
