  • actor_guid (Guid): [Read-Only] The GUID for this actor.

  • affect_distance_field_lighting (bool): [Read-Write] Controls whether the primitive should affect dynamic distance field lighting methods. This flag is only used if CastShadow is true. *

  • allow_tick_before_begin_play (bool): [Read-Write] Whether we allow this Actor to tick before it receives the BeginPlay event. Normally we don’t tick actors until after BeginPlay; this setting allows this behavior to be overridden. This Actor must be able to tick for this setting to be relevant.

  • always_relevant (bool): [Read-Write] Always relevant for network (overrides bOnlyRelevantToOwner).

  • auto_destroy_when_finished (bool): [Read-Write] If true then destroy self when “finished”, meaning all relevant components report that they are done and no timelines or timers are in flight.

  • bake_material_position_offset_into_collision (bool): [Read-Write] Whether to bake the landscape material’s vertical world position offset into the collision heightfield.

  • replay_rewindable (bool): [Read-Write] If true, this actor will only be destroyed during scrubbing if the replay is set to a time before the actor existed.

Does not work with an XY offset map (mesh collision)

  • update_overlaps_method_during_level_streaming (ActorUpdateOverlapsMethod): [Read-Write] 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()

  • use_tessellation_component_screen_size_falloff (bool): [Read-Write] Tell if we should enable tessellation falloff. It will ramp down the Tessellation Multiplier from the material linearly. It should be disabled if you plan on using a custom implementation in material/shaders.

  • virtual_texture_num_lods (int32): [Read-Write] 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.
