Whats the difference between SS2 and the Thief games?
Quite a lot and not much. The games use the same engine so they share the same benefits and faults. The layout is the same and the editor looks exactly the same, but there are some differences. Lots of Thief tutorials apply to ShockEd. And lots of Thief editors can help point you in the right direction. But there are many differences (sounds, objects, how items link) so you may have to do some fine tuning to get a Thief tutorial to work. 8) The first steps you should take to ANY problem you have with ShockEd.
