where is it? I'm trying to find it but it keeps eluding me... can any one tell me where is the skybox texture stashed?!? been working on a map and cant seems to find it PLUS - post skybox textures here if u so desire, it accrued to me that there are no maps set to dusk time nor there are any for early morning, both times are good times, tactical-wise to mount an assault. somebody should have thought of that already... :p
Go into the texture browser, type in skybox/ and it should list the skybox materials. There are 6 per skybox, the name is the section preceding bk/dn/ft/lt/rt/up.
