Hi Jerome, There are very real limits on what I can divine about what may or may not be a problem without getting my hands on your code. Does the existing OpenGL code support multiple graphics contexts? Does it assume a certain OpenGL state? Does it leave OpenGL state in the same state as it left it? Are you telling the OSG about these changes?

Hi Robert, I will use the new cvs version as soon as my code is stable. I find a workaround to apply a specific operation into drawImplementation according to the State context id. However I am facing a pb and I wonder if there is a solution. The bottom line is that the custom drawable exists because I basically call into my drawImplementation func: blackBlox->Render(); where blackbox will perform some volume rendering stuff via opengl code. If I had the source of blackbox, well I would try to make things in the cleaner way, i.e. create 100% osg stuff. But unfortunately it is not the case...So now, what I obseve is that every stuff in blackbox that is not related to textures (like lines) are correctly rendered in both views, but textures related stuff (like texture on a quad) is only visible in one view...I am sure it is related to the context id stuff but do not know where to look...I had already set for each SceneView a different context id ( that is why I can see simple shared geometry in both views )... I hope there is a workaround, even dirty. Any suggestion? Thanks.
