Public function bool Returns true if the user has requested Nanite Meshes to be generated on landscape edit. If we return false then the nanite build will happen either on map save or explicit build.
Public function bool Returns true if we should build nanite meshes in parallel asynchronously.
Public function Virtual Const bool  
Public function void  
Public function void

PrioritizeGrassCreation ( bool bPrioritizeGrassCreation
)

 Setting this to true causes grass instance generation to go wider (multiplies the limits by GGrassCreationPrioritizedMultipler)
Public function void

RegenerateGrass ( bool bInFlushGrass,
bool bInForceSync,
TOptional< TArrayView< FVector > > InOptionalCameraLocations
)

 Can be called at runtime : (optionally) flushes grass on all landscape components and updates them
Public function void  
Public function void Called when components are registered to the world
Public function void

RemoveGrassInstances ( const TSet< ULandscapeComponent* >* ComponentsToRemoveGrassInstances
)

 Remove all grass instances from the specified components. If passed null, removes all grass instances from all proxies.
Public function void  
Public function Virtual void

Tick ( float DeltaTime
)

  
Public function void  
Public function void  
Public function void Wait unit we're able to continue a landscape export task (Max concurrent nanite mesh builds is defined by landscape.Nanite.MaxSimultaneousMultithreadBuilds and landscape.Nanite.MultithreadBuild CVars)
