Variables

	Name	Description
int32	BaseLOD	Base LOD index to generate this LOD. By default, we generate from LOD 0
uint8: 1	bEnforceBoneBoundaries	Penalize edge collapse between vertices that have different major bones.
uint8: 1	bLockColorBounaries	Disallow edge collapse when the vertices do not have a common color
uint8: 1	bLockEdges	Preserve cuts in the mesh surface by locking vertices in place.
uint8: 1	bRecalcNormals	Whether Normal smoothing groups should be preserved.
uint8: 1	bRemapMorphTargets	Remap the morph targets from the base LOD onto the reduce LOD.
int32	MaxBonesPerVertex	Maximum number of bones that can be assigned to each vertex.
float	MaxDeviationPercentage	If ReductionMethod equals MaxDeviation this value is the maximum deviation from the base mesh as a percentage of the bounding sphere.
uint32	MaxNumOfTriangles	The maximum number of triangles to retain
uint32	MaxNumOfTrianglesPercentage	The maximum number of triangles to retain when using percentage termination criterion.
uint32	MaxNumOfVerts	The maximum number of vertices to retain
uint32	MaxNumOfVertsPercentage	The maximum number of vertices to retain when using percentage termination criterion.
float	NormalsThreshold	If the angle between two triangles are above this value, the normals will not be smooth over the edge between those two triangles.
float	NumOfTrianglesPercentage	The percentage of triangles to retain as a ratio, e.g. 0.1 indicates 10 percent
float	NumOfVertPercentage	The percentage of vertices to retain as a ratio, e.g. 0.1 indicates 10 percent
FOnDeleteLODMod...	OnDeleteLODModelDelegate	Transient mutable delegate. If the delegate is bound, the reduction will call it instead of deleting the replaced LODModel. It will be then the delegate owner responsible of the LODModel memory.
TEnumAsByte< en...	ReductionMethod	The method to use when optimizing the skeletal mesh LOD
TEnumAsByte< en...	ShadingImportance	How important shading quality is.
TEnumAsByte< en...	SilhouetteImportance	How important the shape of the geometry is.
TEnumAsByte< en...	SkinningImportance	How important skinning quality is.
TEnumAsByte< en...	TerminationCriterion	The method to use when optimizing the skeletal mesh LOD
TEnumAsByte< en...	TextureImportance	How important texture density is.
float	VolumeImportance	Default value of 1 attempts to preserve volume.
float	WeldingThreshold	The welding threshold distance. Vertices under this distance will be welded.
