[osg-users] Forcing a scene to rebind textures

I am using osg 3.2.1 in a Qt application. Sometimes, for reasons too long to explain here, Qt will destroy the OpenGL context used by a scene. After that I see rendering problems and logs has warnings similar to this one:
WRN: [OSG WARN] Warning: detected OpenGL error 'invalid enumerant' at After Renderer::compile

The rendering issues are caused by missing textures. The geometry looks fine though.
Is there a way to force a complete scene to rebind its textures or do I need to destroy and rebuild the scene?
