Hello Sergey,
Can you elaborate what you mean by fixed to flt? Does this mean that you
need OpenFlight as target format?
I found OpenFlight terribly slow to load and rolled my own converter to
make it paged, optimized etc., but you'll need to stick to osgb for
this, as the flt-format simply does not support all features.
Also I guess the OpenFlight exporter is not fully fledged, so it is more
aiming to translate as much information from the scenegraph as possible,
instead of being optimized towards writing a performance-optimzed flt.
Another hint that I can give you, is to look which options are supported
by the importer/exporter, there might be some room for
optimization/faster loading.
In general: If you have structured databases (e.g. more the one flight,
a master, possibly some externals) optimizing per element can give you
some advantages.
cheers
Sebastian

Thanks, will try but i am kinda fixed with OpenFlight.
Hi Sergey
I'm not familiarized with OpenFlight loader,
But you could use osgconv to convert your model from flt to osgb.
Then use the osgb version in your application. This way, you use an optimized
scene and read the native osg format when you load the model that will speed up
the read process.

Can anybody, please, give me some advice on optimizing AND saving scenegraphs?
I found out that different options of optimizations are only usefull with some
others. Also I'm starting to think that some sorts of optimizations cannot be
saved. Is it true? What should I read on using osgUtil::Optimizer or maybe
somebody can explain it to me? :)
