Hi Andew,
DrawPixels is a real throwback to OpenGL of old and not something I
would recommend using these days - even the OpenGL drivers don't
support natively, and will just use a screen aligned quad.
You'll get better performance if you use a textured quad, and then
screen align it using an
Hi Paul,
I've just checked the osgViewer::Renderer and osgUtil::SceneView and I
can't spot anywhere where the StateSet from the slave Camera's are

Camera StateSet's are ignored. The StateSet attached to the master
camera from

Hi Alessandro,
May I suggest you to use the 2010.2 FBX plugin for 3DSMax? It's downloadable on
the Autodesk web site. I guess it may affect things about transparency and
animations, but it needs to be tested.

Hi Brad,
After the releaseGLContext() could you do a
osg::discardAllDeletedGLObjects() to make sure the cached GL object
handles are all removed, otherwise the new context will think these
handles are still valid and can be reused.

If the simple modification is due to some specific user event (button

Hi all,
I can confirm that this issue exists in 2.9.6 as well and believe Colin's
assessment is correct. Changing the raw pointer to the RequestQueue in the
DatabaseRequest to an observer_ptr and taking a temporary ref when using it
fixes the issue. I'm including a full program that you can use

Fausto,
My project uses Qt widgets as well, so if this is the problem, I'd be

Fortunately/unfortunately, it appears to work for me.
As to the nodes and drawables, all I can say is that there are nodes,
and then, there are nodes.

Thanks for the explanation. I'm still trying to make sense of

Hi,
can you give more detail on what you are adding/removing? Do you use the

keep the drawables? To get more help you'd probably need to make a very
small example that shows the problem...
