Apply Deltas

/**
 * Node that applies vertex deltas from one mesh to another.
 * 
 * Projects morph target deltas between meshes with different topology,
 * using distance thresholds and optional smoothing.
 * 
 * Usage:
 * 1. Connect base mesh and delta source
 * 2. Configure threshold and smoothing settings
 * 3. Output is the deformed mesh
 */

Parameter	Description
Threshold float	Number of nearest neighbors (KNN) used for the affine transformation. Higher values may improve stability.
NormalIncompatibilityThreshold float	Normal threshold at which a triangle is deemed as incompatible. This helps to avoid triangle flipping during Projection.
bMatchMaterialIDs bool	Apply deltas only to vertices that have same material ID.
Subdivision integer	Subdivide the resulted deltas from input files. This usually increase quality and the precision of the final result.
bMatchByUV boolean	Match Base and Morphed files by UVs, ignoring vertex count and order. This shouldn't be used with welded meshes because they don't have their UVs intact.
SmoothIterations integer	Smooth Iterations steps used to Smooth the resulted Projected Deltas.
SmoothStrength float	Smooth Strength used to Smooth the resulted Projected Deltas.
SmoothType enum	Smooth Type used to Smooth the resulted Projected Deltas.
bTransferBoneTransforms boolean	Whether to transfer bone transforms from the target mesh to source mesh.
