Group Sub-Object Level (Cloth)

Groups let you select groups of vertices and constrain them to surfaces, collision objects, or other cloth objects.

• Select an object. > Modify panel > Modifier List > Object-Space Modifiers > Cloth > Modifier stack > Highlight the Group sub-object level

At the Group sub-object level, all selected objects that are part of the Cloth simulation are shown with their vertices visible so that you can select them in an efficient fashion.

When you create or select a group at this sub-object level, the Group Parameters rollout becomes available.

Attention: The concept of a group for Cloth can be applied to both the cloth objects and to the collision objects in the simulation. And when created, groups can then be given unique properties. For example, a group on a collision object can have a different collision offset from the rest of the object. This is a powerful feature when working with groups.

Note: You can select groups of vertices explicitly, with the mouse in the viewports, and you can also specify a soft selection or use a texture map to select vertices using controls on the Group Parameters rollout. See Soft Selection group. In addition, named selection set tools are available at this level.

Groups and Constraints

The main reason for creating a group is to make it a constraint. A group becomes a constraint when you assign its vertices to behave in a particular way: for example, to follow another object or another piece of cloth. Until you make a group into a constraint, the group is described as unassigned.

You create and manage groups, and constrain them, using the controls on the Group rollout. You can fine-tune the behavior of an individual group using the controls on the Group Parameters rollout.
