Нормаль поверхности, с которой мы столкнулись, в мировом пространстве.
no example available in C#
Note: When the CharacterController is colliding with an edge or a corner rather than a flat surface, the reported normal may be different when colliding with BoxColliders than when colliding with MeshColliders. This is due to a limitation in how PhysX handles Capsule/BoxCollider collisions.
