Hey all, me again!

I have a massive 3D array of planes, but i only need to display the
ones surrounding the mouse cursor, then the ones surrounding them ( at
half opacity ). So, I've set up an array/list containing the size and
location i want of all the planes, each entry also contains a list of
surrounding planes.

I then populated a 3D sprite with groups at all the locations in the
array, this is so that I don't end up with all of the planes on screen.
I'm trying to just turn on the ones I need ( planes at the positions of
the surrounding groups from the information in the array ) but I can't
work out an effective way of selecting one of these groups / potential
planes by means of the cursor. collision modifiers don't want anything
to do with groups, so anyone got any ideas?
