Hi Jason, yeah like PaQ shows you can use the "Divide larger than" function in MoI's exporter to ensure that large polygons are diced up into smaller evenly sized pieces.

That can make a result that should be suitable for non-rigid-body type animations without necessarily needing to retopologize.

Certainly if you have a very specific kind of animation where you want one individual piece to move in a certain way it could be a good idea to retopologize that area though...
