LightLevelOverlay
Shows light levels on blocks. That is it. That is the mod.
Features
- Numbers on blocks so you can see exactly where mobs can spawn
- Color coded: Red (0), Yellow (1-7), Green (8+)
- Renders above foliage so you do not have to squint through grass
- Hides behind walls and only shows what you can actually see
- Fast, cached and optimized so it will not tank your FPS
- Underwater mode for drowned spawn prevention
Platforms
Works on both Fabric and NeoForge.
