# 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 |
