Does you geometry have any degenerated primitives

Next thing I would check would be the consistency

You'll just need to open up a pbuffer graphics context on each GPU and
then render to this.

Your rotor is being placed in the Opaque render bin, which is causing all of
the geometry behind it to be culled out. You need to make sure it is in the

Hi Murray,
The OpenFlight format is pretty crap when it comes to identifying
which objects should be treated as opaque or transparent. The OSG has
to do a best guess based on an alpha values present in colour or

transparent so
