Include

Objects

Drag the objects you wish to be deformed here. Since Deformers can be applied to large groups of objects if they are on the same hierarchy levels, this lets you to avoid having to set one Collision Deformer for each object you wish to deform, and instead use only one deformer for the entire group as well as filter which object you want to include in the deformation.

Here, the Collision Deformer should affect all the sphere objects, but since Sphere 1 and 3 were added to the Include list, only these will be deformed. This way, you don't have to create a Collision Deformer for each sphere.

You can also drag in polygon selections and vertex maps if you want to define only a region of a specific object to deform, which can speed up calculations on complex objects.
