i whant find them and edit whit fotoshop where to find it on my pc ?
and how to set up it in res file ore something that on server other cant download

To create or modify the sky, have a look inside the "\half-life\ns\gfx\env" folder

Those textures can be used as skytexture. If you want to create your own you have to create *.tga files. It doesn't matter what name you use for the files, as long as the bk, dn, ft, lf, rt and up are still in the filenames. HL uses them to position the individual textures

bk=back
dn=down
ft=front
lf=left
rt=right
up guess?

they speak for themselves actually. You can of course open up the map which uses a specific texture to see what front is or something...


If you want to create a resfile, download the zips from custom maps and see what is in there...
