Hi! I kind of new to this, so can anyone give me some tips on how to like
keep the roughness out of my picture? I don't know if any of you know what
I'm talking about, but if you do please help. Thanx!

I believe you are referring to the evil "jaggies". If so you need
to use anti-aliasing when rendering your images. You can turn on
AA by putting the appropriate switch in a .ini file or on the
command line (see the docs for which switch to use). If you are
using the Windows version of the program you should see a window
in the tool bar for setting image size. It also has options for
No AA or with AA you can try to see if it fixes your problem. Also
remember the larger you render your image the more pixels you have
avialable. Larger images will always give better results.

To further compliment Ken's reply:

+a0.2 +r2 +am2 +j1

...on the command-line or...

Antialias_Threshold=0.2  ;+a  with 0.3 is default
Antialias_Depth=2  ;+r  uses integers 1 to 5 typically(?)
Sampling_Method=2  ;+am  the type to use, 1 default
Jitter=1  ;+j  0 to 1  (use +j0 when animating)

put into an INI file can yield fairly good results, just beware of longer
render times the lower +a goes and higher +r goes.  It's all relative to those
settings.
Have a read of your POV-Scene help file or document regarding antialiasing
options.  Important stuff.

Bob
