Visualize chunk performance with beautiful terrain-following overlays. See entity counts, tile entities, and lag sources in real-time. Sculk-themed with particles, waves, and floating holograms. 100% client-side.

See the invisible. Hunt the lag.
Sculk Vision transforms the invisible world of chunk data into a stunning visual overlay. Inspired by the mysterious Sculk from the Deep Dark, this mod reveals the computational heartbeat of every chunk around you.
Press F6 and watch as colored overlays materialize on the terrain, showing you exactly where entities are clustering, where tile entities are accumulating, and where the Warden lurks.
Unlike other diagnostic tools that display flat boxes in the sky, Sculk Vision's overlays hug the terrain. Every hill, valley, and cliff is respected - the colored surface sits directly on top of the blocks, creating a beautiful topographic visualization.
| Color | Status | Meaning |
|---|---|---|
| 🟢 | Perfect | < 50 entities, < 10 tile entities |
| 🟡 | Warning | 50-150 entities |
| 🟠 | Dangerous | 150-300 entities |
| 🔴 | Critical | > 300 entities or > 50 tile entities |
| 🟣 | Loading | Chunk is being generated |
| 🔵 | Sculk | Warden detected or Sculk Catalyst active |
Each chunk displays a hovering hologram with:
Critical chunks emit pulsating cyan waves that ripple outward, making lag sources visible from a distance. The Deep Dark aesthetic isn't just for show - it's functional.
Watch as Sculk Soul particles rise from critical chunks and End Rod particles drift down over Sculk-active areas. Performance meets atmosphere.
Get too close to a critical chunk? Feel the lag. Subtle camera shake intensifies as you approach overloaded areas, giving you physical feedback about problem zones.

Full Mod Menu integration with adjustable settings:
Configuration is saved to config/sculkvision.json
Identify entity-dense chunks causing TPS drops without external tools.
Detect problematic mod interactions on a per-chunk basis.
Find tile entity hotspots in complex contraptions.
Visualize entity accumulation in real-time to optimize kill chambers.
Quantitative MSPT analysis for comparing hardware configurations.
MSPT ≈ (entities × 0.05) + (tile_entities × 0.15) + (sculk_active ? 0.5 : 0)
Note: This is an approximation. Actual server tick times vary based on entity AI complexity and mod interactions.
