Hello again!
I've stumbled across using the FOV functions to make a zoom effect and have read some threads on the subject on these forums so the actual implementation of the function is all right.

However, I'd like to know if it's possible to get an exact zoom amount using these functions, eg. Can I make a zoom scope which is exactly 2X? How would I go about calculating the FOV for a particular zoom level?

Thanks,
Broken_Code

The default FOV is:



So to zoom x2 you simply do:

Is it really that easy? I tried that and it didn't look like 2X zoom, must be my eyes! Thanks for the reply, sorry about the trivial question.

Thanks,

The FOV is an angle, so yes, I believe that's it.

I tried the FOV command, it seems to be offset a little, but that might just be me. You could just move the camera closer?
