PCG Volume¶
APCGVolume — bounding region that runs a PCG Graph inside. See PCG → Volumes and Bounds for the full details.
TL;DR¶
| Property | Effect |
|---|---|
| Graph Instance | The PCG Graph asset |
| Generation Trigger | OnLoad / OnDemand / GenerateAtRuntime |
| Regenerate In Editor | Auto-rerun on property changes |
| Hierarchical Generation | Coarse + fine passes for WP |
| Seed | Per-volume override of randomness |
When to prefer PCGVolume over PCGComponent¶
- You want a distinct bounded region in the level (e.g. forest, town, dungeon clearing)
- You want artists to drag corners to reshape the region
- You want to see the bounds in the viewport without an explicit actor
Use a PCGComponent instead when the bounds derive from another actor (e.g. a building blueprint that procedurally dresses its own interior).
