NavMesh does not working...

Hey everyone...

I am very confused with the NavMesh here in my project... I have an enemy that has a NavMeshAgent attached to it and i baked the terrain... Ok, but now, when i set the destination, my enemy does not "respect" the NavMesh baked and he walks trought the terrain...

I dont know what to do for the character does not walk at the non walkable mesh, because if the enemy do this, he starts to entering the terrain wall...

Sorry about my english, i'm brazilian :) Thanks

OBS: i have NavMeshAgent, rigidbody and collider setted to trigger in my enemy.
