With , you can regenerate or update your blend shape deformations so that any topological changes made to your blend shape base
shapes are also applied to their target shapes. is useful when you have to make topological changes to your base shapes after the blend shape is created.
Note
- produces the best results with polygonal geometry.
- The supports custom normals and UVs.
Topology propagation limitations
- may cause vertex swapping in instances of dense topological data where many vertices are close together. For example, vertex
swapping may occur at your model’s closed mouth. To prevent vertex swapping in this instance, open your model’s mouth before
using .
- may produce undesirable results when performed on selected subsets.
- works with NURBS geometry, but the resulting target shape deformations may not look exactly like those of the base shape.
