Region Settings
Region Settings are stored as TOML and control region-level editor/runtime behavior.
Terrain
Enable terrain rendering for the region and define the default terrain tile:
[terrain]
enabled = true
tile_id = "27826750-a9e7-4346-994b-fb318b238452"
enabled: turns terrain on/off for the region.tile_id: default tile used for terrain rendering.
Preview
You can hide sector geometry in the editor preview by name pattern:
[preview]
hide = ["KeepRoof*"]
*is a prefix wildcard.KeepRoof*matches names likeKeepRoof,KeepRoofA,KeepRoof_Upper.
This is useful in isometric editing when you want to hide roof sectors while working on interiors. These preview filters are editor-only and are not applied in the in-game runtime view.
