How do I get a menu background map to work with Garry's Mod?

[Snickerdoodle]

Ok, so I've created a map like the Half Life 2 Background01.bsp, but I just realized that when I put my background.bsp file in the garrysmod/garrysmod/maps folder, the game doesn't pick it up. How would I be able to tell the game to use the bsp as a background map like the other Source games? The map is finished (and works with HL2's menu), I just want to make sure people can use it in Gmod.

I think you need to create a file called chapterbackgrounds.txt in garrysmod\garrysmod\scripts\ and add the following (assuming your map is called background01):
"chapters"
{
1 "background01"
}

No, I'm pretty sure you add 'mapbackground mapname' to your config.cfg

Thanks guys, I'll try that when I get home.

Wouldn't it be better to make a background video with some of that LUA magic instead? Less lag, faster loadings??

3 reasons for a map:

1. Less lag, a huge VTF is hard to process.
2. Quality, maps have whatever graphics options you have.
3. You can't get dynamic features in an animated VTF.

By the way, I tried each suggestion, it didn't work. What did work was adding stuffcmds to the valve.rc file, but when my game loaded it immediately started the whole create server thing, so I just thought "screw it, too much wait time for a background map". Thanks for the help guys, I'll probably just use this for another wacky game.
