Character Collisions

[3DRebel]

Hi
How does UDK calculate its collsions for characters?

I read that the collsiosn cyclinder is now disabled, so is it through the characters bones? (Vehicles I know use per poly)
If so how does it decide which bones to use?

Also is all of this defined in one of the classes if so which one?
Thanks

Unreal still uses the ****ty cylinders for world collision, but for physical interactions it uses the physics assets:
