Trouble modifying NavMesh

I'm working through the FPS Tutorial. I've added a tree from the models, and would like it to be something the player can't walk through. I have checked the "Navigation Static" checkbox, and re-baked the NavMesh The NavMesh appears to exclude the area around the tree:


However, the player is able to walk right through the tree.

Do I need to do something additional? Or does something else constrain the motion of the player?

 

NavMesh is for AI agent movement and will not affect the player. For that, you need colliders.

 

Thanks much!
