[serge] “draw a feathered mask on the precomp to eliminate the grass from the top part of your ball and animate this mask to follow the ball.”

Yes Serge, good idea. You could also draw a mask at the bottom of the ball, then change Add to Substract, then feather it. I do this all the time when I want to give the perspection that my objects are on grass.

Hope that helped.
