Custom Back Ground

Could someone make me a really complex motion background with music for my start-up screen? I’m talking, like, you know on the Orange Box, how they have those preview boxes for each game in the start-up menu? Like that, but larger and the background. If you want to do this, it has to be the Combine being pushed back by rebels with “Sector Sweep” playing.

Or just tell me how to make on like that.

Those are background maps, which don’t work properly in GMod because it would load the game then the background map.

It can be done using video converted to an animated VTF and carefully-synced sound but it would look and sound horrible

Also not everyone had orange box on console, what did that look like?

At 0:10.

(I think so…)

Yeah, at 0:10.
