6.3. These pages document the 6.3 release, where placeable is now entry (what changed) and PlacementOwner is deprecated (migration). Still on 6.2? Your version's guides ship inside the plugin itself, under addons/grid_placement/guides/; the 6.2 URLs on this site now redirect to this series.

Adapter/contract interface for the terrain placement service (6.0.0-S). 6.0.0-211: object-capability contract that the host queries instead of checking is TerrainPlacementService2D or is TerrainPlacementService3D. The hosted implementation injects the concrete service (2D or 3D) via [PlacementServiceGroup.register_terrain]; the rest of the host and the service group only ever hold the contract type. Capabilities express which dimensions the implementation supports; the factory consults them so a 3D group never silently gets attached to a 2D-only brush flow.
