Improved Navigation Mesh

Valve officially supports a select few maps in their 'Offline Training' mode on Team Fortress 2. However, this guide includes fully working and fixed Navigation Mesh for most official maps. If you're interested, subscribe to the comments on this guide, as I will be updating and adding new maps as they come to my attention and/or are requested.

What's this for?

As you might know, Team Fortress 2 has support for AI bots. You are able to play with these bots by using the "Offline Practice" menu, or through commands while on your own server. Valve also handily added an automated way to generate a Navigation Mesh for bots on maps that don't have any; 'nav_generate'.

The 'nav_generate' command is quite useful, as it automatically creates a file for the user to easily play with bots, however if you've used 'nav_generate' a few times in the past, you might have noticed that it has many flaws. If you've run into this issue, you've likely just given up playing on said map with bots.

You can find a link to the latest '.nav' files in the "Downloads" section of this guide.

For a more general overview, such as which maps are/aren't added, you can check those below.

If you have any issues or want to suggest official or custom maps to be added (please make sure the map isn't listed in the "Unsupported Maps" section of the guide!), please feel free to in the comments, I'm subscribed to the discussion so I will receive a notification when you comment.

NOTE: .bsp map files are not included, those must be retrieved from the original creator.

Payload

King of the Hill

Unsupported Maps

NOTE: This list is not final, and could change multiple times. If you wish to keep up-to-date on what maps are supported or otherwise, subscribe to the comment thread of this guide, as I will be commenting whenever I have updated Nav Mesh files.

Unsupported Gamemodes

Currently, there are several gamemodes that Valve has not added bot support for, including:

• Arena
  
• Mann vs. Machine
  
• Mannpower
  
• PASS Time
  
• Payload Race
  
• Player Destruction
  
• Special Delivery

There are no plans to create improved navmesh for these maps.

Unplayable maps

Although these maps are on supported gamemodes, through testing, bots have major issues playing on these maps, making them unenjoyable and/or impossible to play on with bots.

Control Point (Attack/Defend):

cp_snowplow - (Bots don't seem to understand what to do and walk around the train)

cp_steel - (Bots move between first and last point, not getting much done.)

Payload:

pl_swiftwater_final1 - (RED Bots have trouble navigating when BLU gets to last point.)

pl_wutville_event (BLU bots have trouble pushing the cart.)

Issue Reporting

How to Report an Issue

Trello: https://trello.com/b/d9FkzUrg

If you encounter an issue, use the format below and put it in the comments of this guide.

Format:

----------
Project Version: Version you downloaded
Map: mapname
Issue: Describe your issue here, make sure to be clear and detailed!

Extra:
Use this area to add links to images, videos, GIFs, in-game demos, and nav-mesh area #'s. See below for more information about adding these.
----------

Adding Images/Videos/Demos/etc. to Your Report

Activate cheats by typing "sv_cheats 1" into console, then "nav_edit 1" so that you can clearly show where and what the issue is!

Images/GIFs

You can use a website like Imgur to upload your image or GIF, make sure the affected area is clearly visible.

Videos

YouTube is the best place to upload videos. Make sure the video is Unlisted or Public. If possible, demonstrate the issue by showing how bots act in the affected area.

In-game Demos

Demos can be sent as a better alternative to Videos, sites like Dropbox and Google Drive would be best to use to send the .dem file. Make sure the file is public, not private.

Demos can be recorded using the "record demoname" command. Demos are located in the "Team Fortress 2/tf" folder by default.

Nav-Mesh Area #

Every block of navigation mesh has an ID. These IDs are viewable by activating cheats with "sv_cheats 1" and entering the "nav_edit 1" command into console. Hovering your cursor over a nav-mesh block will briefly display "Area #" followed by the ID. You can provide this ID to give an exact location of the issue.

@Zeroman04 Very sorry! The issue has been resolved.

[Zeroman95]

The main VPK file is no longer available, can you fix it?

[Asteur]

@Tiny Desk Engineer There are a few official maps that don't currently have Navmesh, I am planning to add any missing maps in an update eventually, although the next coming update will include just holiday maps

[Tiny Desk Engineer]

No navmesh for pl_borneo?
