Post-Process Volume Inspector

Post-Process Volume Inspector

Module: Design · Category: LevelDesign · Tool ID: PostProcessVolumeInspector

Scans every Post-Process Volume in the active level and reports priority, blend weight, unbound flag, bounds, active overrides, and warnings. Applies Quick Presets (cinematic, archviz, stylized, horror, mobile, etc.) that set the right bOverride_* flags + values on FPostProcessSettings with full undo support.

---

When to use it

• Auditing a level’s post-process setup — finding which volumes have which overrides active
• Applying a tested preset to one or all volumes
• Pre-shipping check — making sure no volume has 50 unintended overrides
• Quick “give me a cinematic look” via preset

When not to use it

• Don’t use this for runtime PP changes — these are editor-side overrides
• Don’t expect this to author custom PP material chains — for that, use UE’s PP editor

Output

• In-panel volumes list
• PP volume modifications — Apply Preset / Clear Overrides modify volume settings in-place
• Undo — wrapped in ScopedTransaction. Ctrl+Z reverses

Tips & gotchas

• bOverride_* flags matter — a value can be set but the override flag off, in which case the volume doesn’t apply. Presets set both
• Unbound volumes apply globally — surprising if you didn’t author them. The Inspector flags them
• Apply to “New Volume” spawns a fresh APostProcessVolume actor with the preset; useful for layered grading
• LUT preset slot is separate — see LUT Color Grading Baker
