Thanks guys,
Riki - just hit cancel, then once the scene is loaded, open MD and hit Start…then if you want you can save out .mdd files…just hit ‘s’ after youve calculated while you have the MDcontroller selected and it will ask to save 2 files…not sure what order it chooses, it doesnt say which it wants to save…kinda lame.
Mike- Ill whip up a couple more when I can…but basically to get either scene to act like mud, play with the floors settings for Spring and Hold…the higher the spring, the more it wants to keep its shape…the more Hold, the faster it will spring back…yeah i know, backwards! 
…then there is Resistance and Viscosity which will make it stickier or harder…and of course a few others i havent decifered.
…like i said, you tweak one thing, and its fine, tweak another, and what was fine is out of wack, while another aspect may be working…so its alot of mix and match and test!
Honestly Id say Ive put in over 200 hours so far just testing! and thats not including the testing of PFX/HVs!!! 
one other thing, you can tweak and tweak the floor, but then tweak a litte of the balls Friction or Bound (I think fixed objects settings dont work except everything under Skin Thickness) and WHAM, all the floor settings are wacked again…
hmmm…any chance in hell someone could REWRITE the interface for MD, not the actual plugin, but just how we tweak the variables that make up the plugin?..simplify? hell, Id help if ya need some!
Something better be done for LW8…otherwise I really dont know what NT is thinking…
