Add
- Causes the collision to happen from the inside, pushing outward.
Subtract - Causes the collision
to happen from the outside, pushing in.
Subdivide - When selected, causes
the object being collided with to subdivide before collision detection.
This provides a more accurate representation of the colliding shape,
but takes longer to calculate and returns a more complex model.
Delete B - Discards the colliding
object (the object used to make the dent) upon return.
