Root Cause

A Volume component in the scene is missing a VolumeProfile asset, so post-processing effects are disabled.

Workarounds

  1. 98% success Assign a VolumeProfile to the Volume component: Create a new VolumeProfile via Assets -> Create -> Volume Profile, then drag it into the Profile field of the Volume component. Alternatively, use this script: volume.profile = Resources.Load<VolumeProfile>("MyProfile");

Dead Ends

Common approaches that don't work:

  1. Reimport URP package from Package Manager 95% fail

    Reimporting does not assign a profile to existing Volume components; profiles must be created or assigned manually.

  2. Enable post-processing in URP Asset settings 85% fail

    This enables the renderer feature but does not fix missing volume profiles.
