Member Data Documentation

BaseLOD

int32 FSkeletalMeshOptimizationSettings::BaseLOD

Base LOD index to generate this LOD. By default, we generate from LOD 0

bEnforceBoneBoundaries

uint8 FSkeletalMeshOptimizationSettings::bEnforceBoneBoundaries

Penalize edge collapse between vertices that have different major bones. This will help articulated segments like tongues but can lead to undesirable results under extreme simplification

bImproveTrianglesForCloth

uint8 FSkeletalMeshOptimizationSettings::bImproveTrianglesForCloth

Better distribution of triangles on 2d meshes, such as flat cloth, but at the cost of potentially worse UVs in those areas. This generally has little or no effect for mesh regions that aren't laid out on a plane intersecting the origin such as the xy-plane. When this is disabled, the planar regions may simplify to fewer large triangles.

bLockColorBounaries

uint8 FSkeletalMeshOptimizationSettings::bLockColorBounaries

Disallow edge collapse when the vertices do not have a common color

bLockEdges

uint8 FSkeletalMeshOptimizationSettings::bLockEdges

Preserve cuts in the mesh surface by locking vertices in place. Increases the quality of the simplified mesh at edges at the cost of more triangles

bMergeCoincidentVertBones

uint8 FSkeletalMeshOptimizationSettings::bMergeCoincidentVertBones

If enabled this option make sure vertices that share the same location (e.g. UV boundaries) have the same bone weights. This can fix cracks when the characters animate.

bRecalcNormals

uint8 FSkeletalMeshOptimizationSettings::bRecalcNormals

Whether Normal smoothing groups should be preserved. If true then Hard Edge Angle (NormalsThreshold) is used

bRemapMorphTargets

uint8 FSkeletalMeshOptimizationSettings::bRemapMorphTargets

MaxBonesPerVertex

int32 FSkeletalMeshOptimizationSettings::MaxBonesPerVertex

Maximum number of bones that can be assigned to each vertex.

MaxDeviationPercentage

float FSkeletalMeshOptimizationSettings::MaxDeviationPercentage

If ReductionMethod equals MaxDeviation this value is the maximum deviation from the base mesh as a percentage of the bounding sphere. In code, it ranges from [0, 1]. In the editor UI, it ranges from [0, 100]

MaxNumOfTriangles

uint32 FSkeletalMeshOptimizationSettings::MaxNumOfTriangles

The maximum number of triangles to retain

MaxNumOfVerts

uint32 FSkeletalMeshOptimizationSettings::MaxNumOfVerts

The maximum number of vertices to retain

NormalsThreshold

float FSkeletalMeshOptimizationSettings::NormalsThreshold

If the angle between two triangles are above this value, the normals will not be smooth over the edge between those two triangles. Set in degrees. This is only used when bRecalcNormals is set to true

NumOfTrianglesPercentage

float FSkeletalMeshOptimizationSettings::NumOfTrianglesPercentage

The percentage of triangles to retain as a ratio, e.g. 0.1 indicates 10 percent

NumOfVertPercentage

float FSkeletalMeshOptimizationSettings::NumOfVertPercentage

The percentage of vertices to retain as a ratio, e.g. 0.1 indicates 10 percent

ReductionMethod

TEnumAsByte<enum SkeletalMeshOptimizationType> FSkeletalMeshOptimizationSettings::ReductionMethod

The method to use when optimizing the skeletal mesh LOD

ShadingImportance

TEnumAsByte<enum SkeletalMeshOptimizationImportance> FSkeletalMeshOptimizationSettings::ShadingImportance

How important shading quality is.

SilhouetteImportance

TEnumAsByte<enum SkeletalMeshOptimizationImportance> FSkeletalMeshOptimizationSettings::SilhouetteImportance

How important the shape of the geometry is.

SkinningImportance

TEnumAsByte<enum SkeletalMeshOptimizationImportance> FSkeletalMeshOptimizationSettings::SkinningImportance

How important skinning quality is.

TerminationCriterion

TEnumAsByte<enum SkeletalMeshTerminationCriterion> FSkeletalMeshOptimizationSettings::TerminationCriterion

The method to use when optimizing the skeletal mesh LOD

TextureImportance

TEnumAsByte<enum SkeletalMeshOptimizationImportance> FSkeletalMeshOptimizationSettings::TextureImportance

How important texture density is.

VolumeImportance

float FSkeletalMeshOptimizationSettings::VolumeImportance

Default value of 1 attempts to preserve volume. Smaller values will loose volume by flattening curved surfaces, and larger values will accentuate curved surfaces.

WeldingThreshold

float FSkeletalMeshOptimizationSettings::WeldingThreshold

The welding threshold distance. Vertices under this distance will be welded.
