How do i make custom 3d backgrounds for the menu in the hl2 beta?

[Flatterbuckle7]

I've been wanting to experiment with making custom 3d menu backgrounds for the beta version of hl2 for a while, but i haven't found any tutorials on the internet. Can someone help me out?

They are! [Thanks to LeakNet] Just look at the City 17 mod or The Borealis mod. Both of those mods have 3D backgrounds. Im not quite sure how to make ones for the beta, but they are supported [As long that you use LeakNet that is].

Run hammer, make a map with some textures, compile to .bsp and type in console "map_background (mapname)" or if you want 3d background always enabled when you run a game, edit cfg.
