Navigating the View Port
CryEngine2 and Sandbox 2 allow you to seamlessly view your created world from a variety of angles, just as easy (possibly even easier) as you would when actually playing the game.
There are two parts to movement:
Forward, Back, Right, Left
The wonderful combination of keys come into play here: W, A, S, D
Turning
To turn, or rotate the viewpoint, simply right click and drag in the direction you want to go.
Simple, eh? Well, this is a basic tutorial!
