[ Figured out ! ]CharacterController: stay on terrain, bounce on other

I feel quite unsecure about the best (or at least a god way) to implement the physics.
(I'm better at coding, at leas I think so )
What I what is:
* the player, a ball not rotating, to stay on the ground (terrain mesh, and maybe a loop).
* the player bounces on most other objects. most objects are same size not moving, but not static, balls.
* the player to, after initial acceleration, have a constant speed. Except for some sliding when turning.
* player loosing points/health when bouncing. More for larger direction change.
.
My current implementation(modified standard FPC), player turning and speed works.
No bouncing, and FPC climbing on the other balls.
.
This is in Unity5.
Pleas HELP!

I'll managed to figure it out.
The problem was that, for example, CharacterMotor.SetVelocity() don't work if I put in the OnControllerColliderHit()
When I put it in LateUpdate(), it seems to work.
