Hi Paul and Robert,

What you are saying makes sense indeed, I didn't think about that.
I will check that inferring (the database is large and exported from 3DSMax 
using OSGExp) : maybe OSGEXp suffer of some lackings concerning transparency 
issues indeed.
Maybe I have after loading of the .osg (or .ive) to make a quick pass on the 
scenegraph to isolate the TRANSPARENT_BIN affected geometries to associate 
some of them to another (of greater number) bin.

I'll make further inquiries to check that point and see.
I'll keep the mailing list informed of the conclusion cos it may be of 
interest for others.
