Hi J.P,The typical problem is that the scene graph has been set up to unref texture images after apply so when it comes to reloading the texture images there aren't the to download.
should this still happen when I'm completely reloading a scene after the viewer and scene have been deleted completely?
It seems that OSG thinks there is still a valid texture it can use after I've deleted the scene and CompositeViewer.
Running the attached e.g.: ./test cow.osg Constructing PixelBufferObject for image=0x9547928 _maxTexturePoolSize=0 _maxBufferObjectPoolSize=0 Created new TextureObject, _numOfTextureObjects 1 Created new TextureObject, _numOfTextureObjects 1now I click the X on the window and the app deletes the scene and viewer and creates them anew:
_maxTexturePoolSize=0 _maxBufferObjectPoolSize=0 Reusing orhpahned TextureObject, _numOfTextureObjects=1 Warning: detected OpenGL error 'invalid value' after RenderBin::draw(,) Reusing orhpahned TextureObject, _numOfTextureObjects=1 Warning: detected OpenGL error 'invalid value' after RenderBin::draw(,)So it tries to reuse something that's not there? How can I convince OSG to drop all caches/buffers/GL objects?

Delport <[email protected]> wrote:Hi all, I've run into the classic "missing textures" problem when stopping and restarting a compositeviewer multiple times in the same app. From previous threads on this problem it seems to be context cleanup/GL object cleanup that does not get done properly, but I'm just using the normal CompositeViewer and not messing with contexts/windows/sceneviews myself, so I thought the cleanup would be handled correctly. Attached a very slightly modified compositeviewer example. All it does is create/destruct the compositeviewer 5 times. When the viewer is created for the second time, all my textures are gone (just run without any arguments). Can anyone confirm the missing textures? Any hints as to what else needs to be done to make sure everything is cleared/flushed correctly? thanks jp -- This message is subject to the CSIR's copyright terms and conditions, e-mail legal notice, and implemented Open Document Format (ODF) standard.
