Watch a door change visibility
15-second visibility demo · silent · plays when you choose.
Read the video description
An orange observer stands in the left room. The central red door begins closed, opens around 4.5 seconds, and closes again around 10.5 seconds. Visibility changes through the doorway as the obstacle moves. The clip is silent. Recorded with Unity Recorder in Unity 6000.5.6f1 for the 26.8.5 sample showcase; it is a workflow demonstration, not a hardware performance measurement.
gameplay-first visibility
One visibility model for rendering, targeting, exploration, and authority.
Fog of War separates deterministic visibility simulation from presentation. Gameplay systems can ask who is visible and what has been explored while the included URP adapter renders the same state for the player.
Competitive concealment
Drive actor visibility, targetability, selection, and other gameplay decisions from the same visibility state.
Exploration persistence
Track discovered areas separately from current visibility so maps can retain exploration without revealing live information.
Server-authority boundary
Keep authoritative visibility decisions independent of the client renderer and integrate them into networked gameplay.
CPU and GPU presentation paths
Choose the presentation backend that fits the target while keeping the visibility contract stable for gameplay code.
Diagnostics and performance controls
Inspect active sources, obstacles, grid state, renderer settings, and workload instead of treating fog as a black box.
from exploration to competition
Readable world state without leaking hidden information.
Use the same system for conventional exploration fog and for competitive visibility where actors, targeting, and networking must agree on what a player is allowed to know.
guided setup
From an empty scene to trusted visibility.
- 01
Run Quick Setup
Create the default system and a starting vision source from the Kiwi Studios tools menu.
- 02
Declare vision and targets
Add vision sources and mark actors that need concealment or targetability decisions.
- 03
Declare obstacles
Add line-of-sight blockers and bake static scene data where appropriate.
- 04
Choose persistence and networking
Enable exploration storage and optional network integration only where the game needs them.
- 05
Inspect before shipping
Use the debug and performance views to verify the active profile, backend, grid, and visibility state.
explicit system boundary
Deterministic simulation, URP presentation.
Unity 6
Built for Unity 6000.0 or newer and documented around 3D worlds using the XZ plane.
URP display adapter
The included renderer targets URP while gameplay visibility and texture-state contracts remain separate from presentation.
Declared authority
Networking adapters are optional; authoritative games should keep final visibility decisions on the authority that owns gameplay state.
maintained reference
Make hidden information an explicit system.
