Biomes Were Already Plenty
by HumanSadness
Biomes Were Already Plenty stops the Anomaly block from flickering and dragging down frame rates in Biomes O Plenty worlds.
What it does
The Anomaly block in Biomes O Plenty cycles rapidly through random block textures, and that cycling can drop frames when a player stands close to it. This client-side Fabric mod replaces the flickering with a single fixed texture, so the block no longer taxes performance when nearby.
Only the client needs the mod, so a server running Biomes O Plenty does not require it and players may join without it. Installation depends on Cloth Config API, Fabric API and Fabric Language Kotlin, and Mod Menu is optional. The mod is open source under the GNU General Public License v3.0 only, and its source code is public. Builds are published for Fabric and 1.21.1 only, with 1.0.0+1.21.1 as the latest file, dated 2026-03-31.
The source repository also includes notes for developers who want IDE support for Biomes O Plenty classes. Those classes come from the Biomes O Plenty Fabric jar, which is kept out of version control, so it has to be placed in the libs folder before the project will resolve them. Building the project anyway removes the red error text the IDE shows for those classes.
