Make Deflection

This tool creates a low-poly mesh that fits the character mesh and has the same armature modifier. It can be used e.g. as a collision object for simulations. For Genesis 8, the deflection mesh has 506 vertices, 1512 edges, and 1008 faces.

• Offset (mm): Offset the surface from the character mesh.
• Quads: Convert the deflector into a majority-quad mesh.
• Subsurf: Smooth the deflection mesh with a subsurf modifier.
• Shrinkwrap: Shrinkwrap the deflection mesh to the original mesh.

Often we only need part of the deflection mesh, e.g. in a hair simulation it may be enough to keep the head and shoulders. In that case we can delete unused parts of the deflection mesh to reduce its size even further.

The creation of the deflection mesh relies on vertex numbers, so if those have been changed, e.g. by merging geografts, there may be problems. However, if you only have added vertices to the original mesh, e.g. by joining the eyelashes, the deflection mesh is created correctly.

The deflection object is added to a separate collection. That can be used when making a dForce Simulation.

As collision connection, choose the deflection collection.
