Biomes Were Already Plenty
Client-side Fabric mod that stops the Anomaly block from Biomes O' Plenty flickering and tanking your FPS.
Tested on 1.21.1. Will probably work on other 1.21.x versions but no guarantees

What it does
The Anomaly block rapidly cycles through random block textures when you get close to it, which tanks your FPS. This mod makes it show its own texture instead.
Config
Via Mod Menu or .minecraft/config/biomes-were-already-plenty.json
| Option | Default | Description |
|---|---|---|
| Fix Anomaly Block Flickering | true | Stops the block cycling through random block states |
| Freeze Anomaly Texture | false | Freezes the texture on the first frame (requires F3+T) |
Dependencies
- Fabric Loader
- Fabric API
- Cloth Config
- Mod Menu (optional)
Building
Builds without any extra steps. If you want IDE support for BOP classes, drop a BOP fabric jar into libs/ it's
gitignored and not needed to build anyway, it just stops the IDE from displaying evil red texts.
