THanks for the reply Michael,

Here's the file (speaker) I loaded
http://moi3d.com/forum/messages.php?webtag=MOI&msg=4561.17

As I said my laptop struggles, even trying to move it.

My setting are the default settings so my mesh angle is set to 10. I will try other options you mentioned

BTW can you suggest good training material/links to get you up to speed with MoI.
I tried vimeo but videos have no audio etc

Many Thanks

Steve
