Space Background. Majorly Important!!!

[Super Charger]

I Want The Same Background As The ESF Battle Arena.
How Can i Get It And How Do I Put It In My Map Using Hammer?

 

[totalvamp]

if you play that map you allready have the background
search for the env folder and locate the tga files of that background
and in VH you put the name (just the name not like backallybk but backally) in map properties

 

[Optional]

I believe they got the backround at www.planethalflife.com/wadfather . If they don't have that one, then you can find another space one; they also have many textures.
