Nav Mesh Agent

I am trying to use a navmesh agent to make a monster in my game. when i am not playing, he is laying down on the grown, but when i press play he is standing up and i don’t want that

Wrong Tag. That’s not a discussion, it’s a question.
And the solution is simple: Have the NavMeshAgent on an Empty Parent and your Mesh-Root with Animator-Component as Child of this Empty Parent. Then you can rotate the Mesh-Root however you want and the character will be laying down. Just make sure the Rotation on the Empty is (0,0,0).
