    Hey guys –

    Here’s the scene: A golf putter (rigid body) hits a golf ball (mograph rigid body) – sending it moving across a very large square of grass (rigid body) towards the hole (a pill shaped boole using the large square of grass).

    However, when the golf ball gets to the hole (where it should fall in), it instead bounces off of it as if the pill shape making the hole was still there as a primitive object.

    How can I get around this error?

    Like most dynamics simulators, MoDyn does not recognize concave shapes, like the hole in your putting green. The workaround is to make the hole area editable, split it up into individual faces, drop them into a fracture object, give the FO a modynamics tag, and set the tag to affect All.
