I made the grass and got the ball to roll down the hill but I cant get it to interact with the grass particles.
My settings for the ball are collision and soft-body( which makes the ball soft and I dont want that but it is in other tutorials)
then I bake and nothing happens when I play the render animation.
Any ideas?
The particle systen needs softbody enabled. Not the ball.

Thanks that fixed everything!
