UDEPRECATED_WeightToolMeshSelector This class wraps the all the components to enable selection on a single mesh in the skin weights tool this allows us to make selections on multiple different meshes NOTE: at some point we may want to do component selections on multiple meshes in any/all viewports at which time this class should be centralized and renamed to UMeshSelector or something like that.

Structs

Name Remarks
FDirectEditWeightState  
FMultiBoneWeightEdits Store a sparse set of modifications to a set of vertex weights for a SET of bones with support for merging edits.
FPoseChangeDetector  
FRefSkeletonTreeDelegates  
FSingleBoneWeightEdits Store a sparse set of modifications to a set of vertex weights on a SINGLE bone
FSkinMirrorData  
FSkinToolDeformer Data required to preview the skinning deformations as you paint
FSkinToolWeights Intermediate storage of the weight maps for duration of tool
FSkinWeightBrushConfig For saving/restoring the brush settings separately for each brush mode (Add, Replace, etc...) Note: Radius and FalloffMode are stored per-mode for serialization compatibility, but at runtime they behave as shared values — every writer propagates to all four per-mode configs (see USkinWeightsPaintToolProperties::SetSharedRadius / SetSharedFalloffMode) and RestoreProperties forces all four entries into sync on load.
FSkinWeightRelaxBrushAdvancedConfig  
FVertexBoneWeight  
FVertexChangeTracker Sparse first-touch gate over a fixed vertex window.
FVertInfo  
HBoneHitProxy HBoneHitProxy

 Unposes a mesh: for each SourceMesh vertex (or those in VertArray), reads the posed position via GetPosedVertexFunc, removes skin transform, removes morph contributions in MorphTargetWeights using deltas from SourceMesh, and emits the resulting ref-pose position via WriteFunc. SkeletalMesh/SkeletalMeshToolsHelper.h  
Mirror MorphTargetName's deltas on Mesh across Symmetry's plane in place. SkeletalMesh/SkeletalMeshToolsHelper.h  

void SkeletalMeshToolsHelper::SetupPreviewTangentMode ( UDynamicMeshComponent* Component
)

 Sets tangent mode for the provided preview mesh based on if there is a valid tangent overlay. SkeletalMesh/SkeletalMeshToolsHelper.h
