The camera post-process zone layer resolves sphere and box trigger volumes into blended post-process settings. It covers fog, color grading, and depth-of-field settings while reporting deterministic enter, exit, priority, and validation issues.

Runtime Surface#

  • FV2CameraPostProcessSettings carries fog density and color, color-grade intensity and tint, and depth-of-field focal distance and aperture.
  • FV2CameraPostProcessZoneConfig carries default settings and fallback blend durations.
  • FV2CameraPostProcessZoneState carries the camera location, previous active zone id, current blend alpha, and current settings.
  • FV2CameraPostProcessZoneInput carries delta seconds.
  • FV2CameraPostProcessZone defines a sphere or box trigger with priority, settings, blend durations, and active state.
  • FV2CameraPostProcessZoneEvaluation returns the resolved active zone, enter/exit flags, blend alpha, blended settings, and validation issues.

Zone Rules#

  1. Invalid config, state, input, or zone data is blocking.
  2. Inactive zones do not trigger.
  3. Sphere zones use distance from center to radius.
  4. Box zones use absolute local offset within extents.
  5. Overlapping zones choose the highest priority zone.
  6. Equal-priority overlaps keep the earlier zone and report PriorityTie.
  7. Entering a zone reports ZoneEntered and blends toward that zone settings.
  8. Exiting all zones reports ZoneExited and blends back to default settings.
  9. BlendComplete is reported when the blend reaches zero or one.

Post-Process Settings#

The resolved settings blend fog density and fog color, color-grade intensity and tint, depth-of-field focal distance, and aperture. Callers can bind the resolved data to runtime post-process volumes or camera post-process overrides.

Validation Commands#
