Variables

	Name	Description
uint32: 1	bCastShadow	Whether the Spline Meshes should cast a shadow.
uint32: 1	bHiddenInGame	Whether to hide the mesh in game
uint32: 1	bLowerTerrain	If the spline is below the terrain, whether to lower the terrain down to the level of the spline when applying it to the landscape.
uint32: 1	bNavDirty
FBodyInstance	BodyInstance	Mesh Collision Settings
FBox	Bounds	Bounds of points
uint32: 1	bPlaceSplineMeshesInStreamingLevels	Whether spline meshes should be placed in landscape proxy streaming levels (true) or the spline's level (false)
uint32: 1	bRaiseTerrain	If the spline is above the terrain, whether to raise the terrain up to the level of the spline when applying it to the landscape.
uint32: 1	bSelected
FName	CollisionProfileName	Name of the collision profile to use for this spline TODO: This field does not have proper Slate customization.
FLandscapeSplin...	Connections	Directly editable data:
TArray< TSoftOb...	ForeignWorlds	World references for mesh components stored in other streaming levels
FName	LayerName	Name of blend layer to paint when applying spline to landscape If "none", no layer is painted
float	LDMaxDrawDistance	Max draw distance for all the mesh pieces used in this spline
TArray< USpline...	LocalMeshComponents	Spline meshes
FGuid	ModificationKey	Key for tracking whether this segment has been modified relative to the mesh components stored in other streaming levels
TArray< FLandsc...	Points	Spline points
int32	RandomSeed	Random seed used for choosing which order to use spline meshes. Ignored if only one mesh is set.
TArray< URuntim...	RuntimeVirtualTextures	Array of runtime virtual textures into which we render the spline segment.
FInterpCurveVec...	SplineInfo	Procedural data:
TArray< FLandsc...	SplineMeshes	Spline meshes from this list are used in random order along the spline.
int32	TranslucencySortPriority	Translucent objects with a lower sort priority draw behind objects with a higher priority.
int32	VirtualTextureCullMips	Number of lower mips in the runtime virtual texture to skip for rendering this primitive.
int32	VirtualTextureLodBias	Lod bias for rendering to runtime virtual texture.
float	VirtualTextureMainPassMaxDrawDistance	Desired cull distance in the main pass if we are rendering to both the virtual texture AND the main pass.
ERuntimeVirtual...	VirtualTextureRenderPassType	Render to the main pass based on the virtual texture settings.

Overridden from UObject

	Name	Description
void	PostDuplicate ( bool bDuplicateForPIE )	Called after duplication & serialization and before PostLoad.
void	PostEditChangeProperty ( FPropertyChangedEvent& PropertyCha... )	Called when a property on this object has been modified externally
void	PostEditImport()	Called after importing property values for this object (paste, duplicate or .t3d import) Allow the object to perform any cleanup for properties which shouldn't be duplicated or are unsupported by the script serialization
void	PostEditUndo()	Called after applying a transaction to the object.
void	PostInitProperties()	Called after the C++ constructor and after the properties have been initialized, including those loaded from config.
void	PostLoad()	Do any object-specific cleanup required immediately after loading an object.
void	Serialize ( FArchive& Ar )	Handles reading, writing, and reference collecting using FArchive.
