How To Add Custom Maps And Use FastDL On Your BrainBread 2 Server

Your BrainBread 2 server comes with built-in FastDL, so players download your custom maps and content quickly when they join. Everything is automatic: upload your files and restart.

Adding a Custom Map

  1. 1
    Log in to Bropanel and Stop your server.
  2. 2
    In the sidebar, go to Files.
  3. 3
    Open brainbread2, then open maps.
  4. 4
    Upload your map's .bsp file and its matching .nav file. BrainBread 2 needs the .nav file for zombie and NPC movement. Put any materials, models or sounds it needs in the matching folders inside brainbread2.
  5. 5
    Start your server.

Then add the map to your map cycle or set it as the start map, as shown in Change Map.

How FastDL Works

Every time your server starts, it collects your custom files and serves them to players over FastDL. The maps that come with BrainBread 2 are left out, since players already have them.

Folder in brainbread2File types
maps.bsp
materials.vmt, .vtf
models.mdl, .vvd, .vtx, .phy, .ani
sound.wav, .mp3, .ogg
particles.pcf
custom/<your addon>All of the above

If a file you need isn't covered, reach out to a bro and we will add it.

Using Your Own Download Server

If you host your files on your own web server, point the server at it instead.

  1. 1
    Log in to Bropanel and select your server.
  2. 2
    In the sidebar, go to Settings.
  3. 3
    Under Modding, edit Download Redirect URL and enter the web address of your files, for example https://example.com/bb2.
  4. 4
    Click Save & Restart to apply your changes.

Clear Download Redirect URL to go back to the built-in FastDL.
