Hi Robert, I use two way to modify my scene graph. The first one is using the UpdateCallback each time it is possible. The second one is when we are outside the ViewerBase::frame() function. Our application have a lot of threads and i use a mutex to be sure the OSG tree is never ac

Hi, I have a similar problem when i create an OSGTerrain node in a multithread configuration. The crash occur in the init function of the GeometryTechnique class. Note i use OSG 3.2. To solve this problem, i made a small modification to OSG itself. I replace the line if (!_cur

I see my limitations make it impossible to evaluate if it is hardware/built related. But I have figured something out something, how should I set the StateSet for the scene-data. I removed the current added stateset and now the scene isn't rendered in any of the views. How should the StateSet be se

HI Partrick, There are just too many unkowns about what you are doing and what system you are using to know what might be going wrong. What hardware are you using? What OS? Have you tried other systems and other OpenGL drivers? Did you build the OSG yourself? Have you tried OSG-3.2? In princi
