I think I still haven't got the slightest clue what you're trying to 
achieve. I guess you may need to re-word the question. Try being less 
"hectic" in your explanation.

You may also want to try posting in povray.general or povray.newusers, 
as this newsgroup is specifically for questions regarding the Windows 
version of POV-Ray, so you have a smaller audience here.

A sample scene of what you managed to achieve so far might be helpful as 
well, or a drawing of what you're trying to achieve, or something along 
that lines. Give us some help to visualize your problem.
