Sculk Vision
by maxlananass
Sculk Vision overlays chunk data on the terrain around the player, showing entity counts and tile entity lag sources in real time.
What it does
Sculk Vision draws colored overlays that follow the terrain, marking where entities cluster and where tile entities such as hoppers, chests and furnaces accumulate. A floating hologram above each chunk lists its entity count, total entities, tile entity count, estimated MSPT and approximate tick time share, next to a status light. The overlay is toggled with F6, and the themed visuals are inspired by the Sculk and Deep Dark content of the base game.
The mod is client-side only, so the server and other players do not need it. Sculk Vision requires Fabric API and is published for Fabric only, across 12 release versions 1.21 – 1.21.11, under the Creative Commons Attribution Non Commercial 4.0 license, which is not open source. Mod Menu is optional and adds an integration screen with adjustable settings. The estimated tick times are approximate, since real server tick times vary with entity AI complexity and mod interactions.
Key features
Entity and tile entity counts
Overlays show the number of entities and tile entities per chunk, so clusters of load are visible in place.
Lag estimates per chunk
Each chunk displays an estimated MSPT and an approximate tick time contribution alongside a status indicator.
Toggleable visual effects
Screen shake, particles and holograms can each be switched off, and the overlay height offset can be adjusted.
Sculk-themed display
Terrain-following overlays use particles, waves and floating holograms in a style drawn from the Sculk theme.
