Editor Properties: (see get_editor_property/set_editor_property)

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

• 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.

• default_update_overlaps_method_during_level_streaming (ActorUpdateOverlapsMethod): [Read-Only] Default value taken from config file for this class when ‘UseConfigDefault’ is chosen for ‘UpdateOverlapsMethodDuringLevelStreaming’. This allows a default to be chosen per class in the matching config. For example, for Actor it could be specified in DefaultEngine.ini as:

  [/Script/Engine.Actor] DefaultUpdateOverlapsMethodDuringLevelStreaming = OnlyUpdateMovable

Tick functions can be configured to control whether ticking is enabled, at what time during a frame the update occurs, and to set up tick dependencies. https://docs.unrealengine.com/latest/INT/API/Runtime/Engine/Engine/FTickFunction/: AddTickPrerequisiteActor(), AddTickPrerequisiteComponent():

• relevant_for_level_bounds (bool): [Read-Write] If true, this actor’s component’s bounds will be included in the level’s bounding box unless the Actor’s class has overridden IsLevelBoundsRelevant

• render_custom_depth (bool): [Read-Write] If true, the Landscape will be rendered in the CustomDepth pass (usually used for outlines)

• 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.

• simple_collision_mip_level (int32): [Read-Write] 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] Controls how to handle spawning this actor in a situation where it’s colliding with something else. “Default” means AlwaysSpawn here.

• sprite_scale (float): [Read-Write] The scale to apply to any billboard components in editor builds (happens in any WITH_EDITOR build, including non-cooked games).

• static_lighting_resolution (float): [Read-Write] The resolution to cache lighting at, in texels/quad in one axis Total resolution would be changed by StaticLightingResolution*StaticLightingResolution Automatically calculate proper value for removing seams

• streaming_distance_multiplier (float): [Read-Write] Allows artists to adjust the distance where textures using UV 0 are streamed in/out. 1.0 is the default, whereas a higher value increases the streamed-in resolution. Value can be < 0 (from legcay content, or code changes)

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

• tessellation_component_screen_size (float): [Read-Write] Component screen size (0.0 - 1.0) at which we should enable tessellation.

• 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. bGenerateOverlapEventsDuringLevelStreaming, DefaultUpdateOverlapsMethodDuringLevelStreaming, GetUpdateOverlapsMethodDuringLevelStreaming():

• use_dynamic_material_instance (bool): [Read-Write] When set to true it will generate MaterialInstanceDynamic for each components, so material can be changed at runtime

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