Hammer tool question! again...

So I have almost completed my surf map for Counter-Strike 1.6 and the only thing I will have to do now is to change the skybox texture…
At the moment it’s somekinda desert texture but i want to change it into the snowy one like in cs_office.

I’ve googled for help but I only found for Source SDK… I have Hammer Editor 3.4…

So…

…anyone?

…please?

And in future you’d get better answers in the Mapping forum

There’s only a forum for GARRY’S MOD mapping…

I’m making CS1.6 map

That’s also for Goldsrc games aswell.

It’s a forum for mapping in Hammer and variations of Hammer.
