Remarks

A Geometry Cache is a piece/set of geometry that consists of individual Mesh/Transformation samples. In contrast with Static Meshes they can have their vertices animated in certain ways. *

Variables

Functions

	Name	Description
void	AddTrack ( UGeometryCacheTrack* Track )	AddTrack
float	CalculateDuration()	Calculate it's duration
void	ClearForReimporting()	Clears all stored data so the reimporting step can fill the instance again
int32	GetEndFrame()	Get the end frame
int32	GetFrameAtTime ( const float Time )	Get the Frame at the Specified Time
FString	GetHash()	Get the hash of the meshes data of the GeometryCache
void	GetMeshDataAtTime ( float Time, TArray< FGeometryCacheMeshData >& ... )	Get the mesh data at the specified time
int32	GetStartFrame()	Get the start frame
void	SetFrameStartEnd ( int32 InStartFrame, int32 InEndFrame )	Set the start and end frames for the GeometryCache

Overridden from UObject

	Name	Description
void	BeginDestroy()	Called before destroying the object.
void	GetAssetRegistryTags ( TArray< FAssetRegistryTag >& OutTa... )	Gathers a list of asset registry searchable tags which are name/value pairs with some type information This only needs to be implemented for asset objects
FString	GetDesc()	Return a one line description of an object for viewing in the thumbnail view of the generic browser
bool	IsReadyForFinishDestroy()	Called to check if the object is ready for FinishDestroy.
void	PostInitProperties()	Called after the C++ constructor and after the properties have been initialized, including those loaded from config.
void	PreEditChange ( FProperty* PropertyAboutToChan... )	This is called when a property is about to be modified externally
void	Serialize ( FArchive& Ar )	Handles reading, writing, and reference collecting using FArchive.
