Stitch

Mesh Morpher has the ability to stitch two morph targets between two meshes.

Option	Description
Boundary Threshold	Distance Threshold at which the boundary vertices are coincident
Use Edge Closest Point	Whether the correspondent vertices are glued to the closest point on edges.
Vertex Threshold	The Maximum Threshold between the original position and the welded position
Merge Vertex Tolerance	Edges are coincident if both pairs of endpoint vertices are closer than this distance
Merge Search Tolerance	Edges are considered as potentially the same if their midpoints are within this distance. Due to floating-point roundoff this should be larger than MergeVertexTolerance.
Merge Only Unique Pairs	Only merge unambiguous pairs that have unique duplicate-edge matches
