Hi Robert/Paul
In answer to various questions Yes osgviewer flight1_0.flt (see attachment) causes the crash. The file is only 6 polygons. If I reduce the number of polys or change the structure, then the results become unpredicatble, sometimes working other times not. It seems to be the last polygon in the model – f801 that seems to cause the problem. I went through the stages suggested by Paul 1) specifying the preserveFace=1 allowed the file to load successfully 2) I saved the file as a .osg 3) I loaded the file flight1_0.osg and it loaded successfully So I assume from Paul’s comments that the best place to look for a problem would be in the FLT loader?

Load the FLT file, but specify the "preserveFace" option, which causes the FLT loader to not run the Optimizer. App now has an unoptimized scene graph. >2.
