Short aswer: I think it has to do with the LGEO-parts which look
beautiful but are programmed very complex and are a bit buggy. In some
transparant parts these bugs cause a grainy or noisy finish.
Long answer: I think it has to do with the LGEO-parts which look

transparant parts these bugs cause a grainy or noisy finish.
This has to do with 2 objects (in the same part) that share one or more
sides on the same coordinates. This causes POV-Ray to get confused about
wheter or not making a pixel transparant. Small changes in view angle
(as happening in Ben's animation) can make the transparant part look
lighter or darker.
Solutions are:
A - bugfix the LGEO parts and delete useless objects or,
B - embed Anton Raves' code in your LDraw-parts that cause problems.
Anton's parts are less complex and look as beautiful (or better) as
LGEO, or,
C - convert the complete LDraw file into Anton Raves parts
(http://www.antonraves.com/converter.php),
D - Life with it.
Good luck, Jeroen
