Hi Peter,

I have to see how the modeler got the result I see exactly... :-)

I'll try to get a simple model that exhibits the problems I see.

That would be the combination of INDEX_MESH | VERTEX_POSTTRANSFORM | 
VERTEX_PRETRANSFORM in the osgUtil::Optimizer. I've seen it work 
wonders, yes. So I may consider running the Optimizer with some flags 
including these on any exported file. I'll see.

Thanks,
