Vellum Trampoline - How to get more bounce?

Recommended Posts

Hey there, I'm currently trying to get a trampoline effect in Houdini. My current set up is using a grid as the trampoline, and I have a sphere falling onto the trampoline with a mass of 15 all in a vellum cloth set-up. Solver has 10 substeps. 

I get a small initial bounce, then it loses all bounce after that. I've tried increasing substeps, messing with the trampoline cloth stiffness and bend, lowering the rest length, etc. I can't seem to get a stronger bounce than what I have now. I'd love to maintain the first bounces "bounciness" with all the following bounces. Any help would be very appreciated!

Scene file attached and test vid attached.
