Create and show navigation mesh?

Hi guys,

I can't seem to figure out how to create and view the navigation mesh in a simple test level. My setup is as follows:

• Three entities: [A] Capsule with navigation, character physics, etc. [B] Obstacle with static physics, and a collider. "Sunk" into the terrain halfway. [C] Simple entity with transform only, to serve as a waypoint.

• [A] has a LUA script to move to [C]. [B] is between entity [A] and [C].

• Navigation area created to enclose [A], [B], and [C]. It is "sunk" a little below the terrain.

Expectation: For [A] to nav around [B] to reach [C].

Result: When I hit Play, [A] moves toward [C], but is stopped by [B].

I am unable to view the navigable area, regardless of the value of 'ai_DebugDrawNavigation' (I've set it to 0 through 5, no luck).

Any thoughts? I'd like to start integrating navigable meshes into my level, but I'm a bit stuck at the moment.

Thanks!
