  • simple_collision_mip_level (int32): [Read-Write] Simple Collision Mip Level: If set higher than the “Collision Mip Level”, this specifies the Landscape LOD to use for “simple collision” tests, otherwise the “Collision Mip Level” is used for both simple and complex collision. Does not work with an XY offset map (mesh collision)

  • spawn_collision_handling_method (SpawnActorCollisionHandlingMethod): [Read-Write] Spawn Collision Handling Method: Controls how to handle spawning this actor in a situation where it’s colliding with something else. “Default” means AlwaysSpawn here.

Value can be < 0 (from legcay content, or code changes)

  • tags (Array(Name)): [Read-Write] Tags: Array of tags that can be used for grouping and categorizing.

  • update_overlaps_method_during_level_streaming (ActorUpdateOverlapsMethod): [Read-Write] Update Overlaps Method During Level Streaming: Condition for calling UpdateOverlaps() to initialize overlap state when loaded in during level streaming. If set to ‘UseConfigDefault’, the default specified in ini (displayed in ‘DefaultUpdateOverlapsMethodDuringLevelStreaming’) will be used. If overlaps are not initialized, this actor and attached components will not have an initial state of what objects are touching it, and overlap events may only come in once one of those objects update overlaps themselves (for example when moving). However if an object touching it does initialize state, both objects will know about their touching state with each other. This can be a potentially large performance savings during level loading and streaming, and is safe if the object and others initially overlapping it do not need the overlap state because they will not trigger overlap notifications.

    Note that if ‘bGenerateOverlapEventsDuringLevelStreaming’ is true, overlaps are always updated in this case, but that flag determines whether the Begin/End overlap events are triggered. see: bGenerateOverlapEventsDuringLevelStreaming, DefaultUpdateOverlapsMethodDuringLevelStreaming, GetUpdateOverlapsMethodDuringLevelStreaming()

  • used_for_navigation (bool): [Read-Write] Used for Navigation: Hints navigation system whether this landscape will ever be navigated on. true by default, but make sure to set it to false for faraway, background landscapes

  • virtual_texture_lod_bias (int32): [Read-Write] Virtual Texture Lod Bias: Bias to the LOD selected for rendering to runtime virtual textures. Higher values reduce vertex count when rendering to the runtime virtual texture.

  • virtual_texture_num_lods (int32): [Read-Write] Virtual Texture Num Lods: Number of mesh levels to use when rendering landscape into runtime virtual texture. Lower values reduce vertex count when rendering to the runtime virtual texture but decrease accuracy when using values that require vertex interpolation.
