The shape used by the Simulate Rigid Bodies node for determining collisions.

If this attribute is not defined, Shape is used instead. Setting this value allows you to use a simpler shape for collisions than for rendering and display, reducing the amount of computation required.

Only Box and Sphere are valid values:

• Disc and Rectangle are approximated by Box.

• Cone, Cylinder, Segment, Capsule, and Blob are approximated by Sphere.

• Point is approximated by a very small Sphere.

• Instances are approximated by their bounding box.
