Hello- We are seeing an interesting problem that we can not track down. Several previous postings have been similar but not quite what we are seeing. We are hoping someone can point us in a possible direction to find a solution.
We have an OSG/QT application using multiple windows with views into the same scene graph. We use multiple instances of the Viewer to do this. We are seeing issues in the second/third/etc window for models loaded in containing textures. The textures do not load and we get "Warning: detected OpenGL error 'invalid enumerant' after applying attribute Texture2D" when the second window is opened. However if we create an object at runtime, say a sphere, and apply a texture to it, the second/third/etc window do not have problems with it. If we save out the node we created to an IVE file and reload it, the problem is there. I have tried to duplicate this problem using the osgviewer QT example such that I have a simpler code base to work with, and I can't. I have made this example more complex, adding features to it to replicate our code (HUD, textured background, our update loop for updating dynamic transform nodes and camera positioning, our state settings, thread settings, etc). We seem to have an issue with PagedLOD too in our application for the second/third windows. I hope this issue is related so if we focus on the texture problem, maybe the other will be solved. We are using OSG 2.4 and currently QT 3.3 (hope to be moving to 4.X soon). We are seeing this on both our Linux and Windows machines. Thanks for any suggestions or insight into this.
