FOW Image Effect

The FOW Image Effect components draw the fog on a camera in the Built-In (Legacy) Render Pipeline. Add one to your main camera.

Note

These components are for the Built-In pipeline only. For URP and HDRP, the fog is injected via a render feature / volume instead — see Render Pipeline Setup.

Which One to Use

Component Use for
FOW Image Effect Opaque 3D (most cases). Renders the fog at the opaque stage. This was the only option before update 3.0.
FOW Image Effect 2D.

Behavior

  • Requires a Camera component (added automatically).
  • Runs in the editor (ExecuteInEditMode) and is allowed in the scene view, so you can preview the fog without entering play mode.
  • Automatically enables the camera depth texture mode it needs.
  • If no Fog Of War World is present (or its appearance is set to None), the camera image passes through untouched.

Setup

See Render Pipeline Setup for the full walkthrough.
