@Ross,
I would probably load them like you're saying, and make sure they have
proper names. Then I would retrieve them from the library and clone
them whenever I need a new one:
var new_mesh : Mesh;
new_mesh = Mesh(AssetLibrary.getAsset('barrel')).clone();
I'm not sure how well the clone() methods are implemented at this
point. If it doesn't work, you can create your own clone-like
functionality like so:
var original : Mesh = Mesh(AssetLibrary.getAsset('barrel'));
var copy : Mesh = new Mesh(original.geometry);
Hope this helps!
Cheers
/R
