It's just to remove this whole block:

	// 3. If there are no children, the node is ignored
	if( osggroup->getNumChildren() == 0 ){

         /// ...

	}

in group.cpp.

Maybe I sent it before, I can't remember, but I can't send it to you 
right now because Max doesn't start anymore (grrr)

You can see the export dialog for the Max exporter here:

http://sourceforge.net/apps/mediawiki/osgmaxexp/index.php?title=Documentation#Export_options

I'm not suggesting that you replicate the UI completely, in fact I like 
the UI you have for the Maya exporter. But look at the options under 
"Optimize" in that dialog, it can give you some ideas.

The one I would add is the great optimization INDEX_MESH | 
VERTEX_POSTTRANSFORM | VERTEX_PRETRANSFORM which basically uniformises 
and merges all primitive sets in a geometry. In combination with 
MERGE_GEODES AND MERGE_GEOMETRY, it's a great way to reduce the number 
of draw calls, which are a major bottleneck of ours.

If you wanna try creating the ui on your own, its very easy :-)

I may help with this if time permits later, for now I'm just trying to 
get a first version of a working content pipeline set up... :-)

Thanks,
