Hi Alexandre, I have some intial finding w.r.t the lighting turning off in the scene when you use:
view->setLightingMode(osg::View::NO_LIGHT); The reason why this unlights the scene, is because the scene graph setup lacks any enabling of GL_LIGHTING, and it was only visible because when LightingMode != NO_LIGHT that the internal SceneView would enable GL_LIGHTING by default. So not getting any lighting in the scene is actually correct for the viewer and scene graph setting. So rather --addslave revealling a bug, it actually makes the code work as you've set the scene graph/viewer up as. Adding the following line to osglight.cpp fixes this problem, as it explicitly enables lighting for the scene you want to light. rootnode->getOrCreateStateSet()->setMode(GL_LIGHTING, osg::StateAttribute::ON); Now, the question for me is why adding the slave fixes things, and why without the slave the defaults are having an effect. It looks like an order of initialisation issue - i.e. the master camera and it's Renderer intialize with the defaults of the HEADLIGHT which enables the GL_LIGHTING mode by default, but the later reset of the LightingMode to be NO_LIGHT doesn't actively change the GL_LIGHTING mode/enable disable. I will continue to look into this, but once I do fix it the behaviour we should see is that there will be no lighting enabled by default if you do NO_LIGHT. I hope this makes sense.
