Blueprint
“Terrain Save Reference”, a Blueprint type

Description

Pass it to LoadTerrainFromSlot; a different or damaged file is refused.

Each save of a slot writes a new file (<Slot>.<n>.tsterrain) and deletes the older ones that no loaded terrain pages from, so a reference goes stale once its slot is saved again: keep the newest.

Functions

  • IsValid

    A reference to a save: it names a file.
