Make a generic Start script with a camera in it.
Refer to the AUMs (Acknex User Magazine) for working examples.
Then every time you want to test a new scene out, add the script, apply the camera action to an object in the scene (just a small ball or box or something) and check it out.

Ive got one of Georges lying around somewhere in my hard drive so as soon as I find that, I'll past it here for you to check out.

[EDIT]
OK, copy/paste this into Word (not office word!)
Then save as "TestScript.wdl" including the "" marks (dont know lite c)
Then place a small onject in your level and attach the "Freecamera" action to it, update entits or build then go.


Aslo has some basics in it like fps counter, version used etc.

When in runtime, press c to use camera.
Dont be scared to play with values.
