Adapting Hammer instructions to JACK is not that hard. JACK is a very close to Hammer 3.x in its interface. In fact they're way more similar to each other than any one of them to, say, TrenchBroom or NetRadiant.
Setting up for Blue Shift is not much different than setting up for any other GoldSrc game/mod:
- Set up mod directory to
<steam library>/steamapps/common/half-life/bshift_addon/
- Replace Half-Life's FGD with Blue Shift's FGD
- Add Blue Shift's WADs, in particular,
barney.wad
and its own decals.wad
The only important difference particular to Blue Shift is to run bspfix (
