Why can't I see bot navigation mesh in TF2?

I have turned on sv_cheats 1 and run nav_generate on the server. Then I set nav_edit 1 from within TF2 (client-side), but no mesh appears. I've added bots, and they clearly follow the generated nav, so it does exist, I just can't see it.

I've followed this tutorial and looked at various guides and forum posts, but no luck.

I've tried turning on nav_edit 1 on the server side instead, but it starts an infinite loop of error messages saying:

UTIL_getlistenserverhost() called from a dedicated server or single-player game

I've tried different maps and different map types, no difference.

I've tried two different computers, no difference.

What am I missing or doing wrong? Is there a graphics setting I need to change, maybe?

How do you make a nav mesh in tf2?

Unpause the game and look at the ground, (it doesn't matter where) and then re-open the console. When you unpause, if you did it right, you'll see a purple triangle made out of wireframe. Open the console once more and then type "nav_generate". The Nav should generate now.

How do I make bots walk in tf2?

Type sv_cheats 1 in the console, then type nav_generate . As soon as you type this in, your game will lag for a bit, so you'll have to wait. This will make the bots work on most maps (except for Doomsday, MVM, Arena and Payload races), but on all others they'll go for the objective.
