Getting the normal

Physics

Hi,

I have a rigid body with a collider, entering in contact with a trigger.
How can i get the collision contact normal of where the rigid body got in contact with the trigger ?
I know if i converted the trigger to a normal collider, i would get this trough the collision,but i need this as a trigger.
any ideas ?
thanks

The trigger object and the rigidbody should still both have a collider, otherwise how would they collide?
