Hi Robert,
yes I also tried on this little code to make an osgconv, that's the way I used to find that the problem comes from the PrimitiveSets. The file generated by osgconv merges the two primitiveSets in only one, ie : Before : PrimitiveSets 2 { DrawArrays TRIANGLES 0 18 DrawArrays TRIANGLES 18 18 } After: PrimitiveSets 1 { DrawArrays TRIANGLES 0 36 } The problem is that my database is a multifile ive database (962 ive files) with external image files (1669 dds files) so I have no clue how to correct these errors on the whole database (because this error happens ofter than once, nearly on each roof of the houses in the database >:o ). I don't know how the database has been generated, we bought it several years ago for our simulation laboratory, so the creation process is not known.

I still have this kind of problem with the trunk of OSG, and I don't know why this really happens... The only actual solution is OSG_OPTIMIZER="DEFAULT ~MAKE_FAST_GEOMETRY"I have just tried running your model on my Linux box and I get the "Warning: detected OpenGL error 'invalid enumerant' at after RenderBin::draw(..)" when the optimizer is it's default form. Curiously if I run osgconv on the model which will run the optimizer and then write out a new file, if I load this new file it works fine - even without changing the optimizer options.This behaviour would suggest that the optimizer is creating some scene graph state that generates invalid OpenGL data when rendering but this state isn't saved and reloaded. From your investigation it'd look to be the MAKE_FAST_GEOMETRY option that is introducing this issue, however, the odd thing is the resulting .osg that osgconv generates still has the vertex indices in the scene graph. BTW, how did you generate the original model with vertex indices? vertex indices are very much a deprecated and strongly recommend not to use feature of the OSG that is only still available for backwards compatibility.
