Look in the editors depot for sum really gud tut's on this.
To put it simply, camera.sqs lets you make better cutscenes than those crappy trigger cameras.
Anyway move the camera around and than once you have ur angle or shot u want press ctrl-c, alt tab out of OFP, open up notepad, and press ctrl-v.
Now u shud see a load of code etc. Thats the basics, im not on my main comp so i cant give u any examples or the code u need at the beginning of each script.
Read the tuts though first.
