What is the easiest way to simulate trampoline? I've been fiddling with physics for about three hours now, I'm trying to create a trampoline physics scenario, or a stretched cloth with a pinned diameter catching a falling object.

My falling objects react with cloth, but keep falling through. Is this only possible via manual animation?
Speaking to trampoline effect (simple one) ...


falling object with two keyframes (start / end Z position) with Dynamic Effect  Elastic (T) set in Graph Editor with first keyframe selected
"trampoline" worked better for me with Soft Body sim (Mass zero, Goal > Strength 1)




To protect object from penetration try for object Collision > Outer Thickness increase value a bit or for "trampoline" increase Solver > Step Size.
