I would like to use offscreen rendering with the LagrangianParticleTracker plugin but when I configure with:  
PARAVIEW\_BUILD\_QT\_GUI OFF  
the LagrangianParticleTracker plugin is no longer an option. Additionally, the LagrangianParticleTracker plugin is not an option with the Kitware-provided osmesa binaries.

Is this a bug with plugin dependencies or a fundamental limitation of the LagrangianParticleTracker plugin?

Thanks,  
Andy

Indeed, LagrangianParticleTracker is a Qt+VTK plugin. It could fallback to VTK only plugin when Qt is not available. This would be quite an easy tack to do if you have some CMake knowledge.
