My second try with Discobob's plugin. This time I'm using the Pro version (more options with it), and DS3A-64bit program.
I changed it up some, changing the stairs to a ramp, making the ball bigger and heavier, and using a different brick wall setup.
My thanks to Josh (Discobob) for his e-mail with tips on how to use some of the settings for better stability, particularly with the wall...! More to come....
