Library Creator Questions

Creating a new library with several trees. My question is about the ball collision properties. I assume the trunk would be "solid-round-vertical" and leaves would be "pass thru-hemisphere". Assuming those are correct, I'm confused about what values the restitution energy and slip should be for each. Thanks in advance!

Jim!
Wish I could help but I never used the library creator. Hopefully Brian can help out when he sees this post.

I have some values I used for libraries written on this page:
http://www.zagerdesign.com/golf_design/ ... erties.htm
It's been so long (over 10 years) since I've created a library that I don't remember how I arrived at those values but for trees I have that I used:
Trunks
Ball ricochets off in a different direction without losing much speed.
Collision Type: Solid-Round-Verticle
Restitution: 40
Slip: 95
Branches
Ball generally holds its line but loses most of its speed.
Collision Type: Pass Thru-Flat
Restitution: 25
Slip: 30
