Hello everyone,
I'm working on a project where I need to load and display OpenFlight files.
I've found that some of my test files make my program crash. The file is loaded
correctly but it crashes when rendering. I also noticed that osgviewer doesn't
make it with this files.
After debuging a little, I've found out that the method
IndexedLightPoint::readRecord (RecordInputStream& in, Document& document) was
setting the osgSim::LightPointNode's maxPixelSize to zero. This is causing a
index out of range exception afterwards in the draw traversal...
I've solved this problem by simply adding a check for zero before setting the
maxPixelSize read from the file.

With this simple patch the flt files that made osgviewer to crash are now
loaded and displayed correctly.
I hope this helps.
Thank you!
