Hi Stephane,
Stephane, try to put an empty shader program on the cow, just like this:
cow-getOrCreateStateSet()-setAttribute(new osg::Program(),
osg::StateAttribute::ON);
I think this could help you.
And if not then just
Stephane,
Have you tried running with no optimizer? A while ago I dimly remember
encountering something similar with the optimiser doing funny things with
empty nodes that had state changes...

I was pretty sure that this would helps. This is a problem which I have
already encountered long time ago during the development of osgPPU.
The problem is that there exists an apply() method for StateAttributes

Woops, I forget to send the other buggy scene.

OK, maybe I have to read through the complete osg code again and again.
Hi,
coming to this thread late, sorry if redundant.
There occasionally creeps up a question about osg::Program state
leakage, and I could have sworn it was fixed, but maybe not.
Is the problem fixed adding an empty osg::Program at the very root of
the scenegraph? Such state leakage seems due
right, but not a disapply so much as a pop of state to a baseline,
and the problem is that baseline is currently undefined. So it seems
the answer is to provide that missing baseline state in osg::State
above the root, so that state popping properly restores.
I wish I could create and submit the
Hi Art,
As I previous explain before the apply of the default setting is done
by apply a default constructed StateAttribute, this applies to
osg::Program just as it does any other StateAttribute. This default
constructed StateAttribute is applied when all other entries of that

Hi Robert,
OpenSceneGraph have a strange behavior when I set a shader and an
uniform variable on the state set of a geode which have no drawable.
I write a very simple osg scene file to show you my problem (see the

I have a group which have 2 children :

Hi Stephane,
When I run
osgviewer scene.osg
I get a red cow, which looks correct. I'm using the SVN version of
the OSG under 64bit Kubuntu 7.10 on a Quad core Intel chip with NVidia
drivers/7800GT.
Robert.

I have a red cow too, but it is not correct !
I send to you a graphical view of the scene graph in the file.
I put the shader on the state set of anEmptyGeode, and it is applied
on the cow. It is not correct at all !

Hi Robert,
There is another strange thing about this.
If you run
osgviewer scene.osg
and you press the 's' key, you could see that the statistics are red.
So, the shader is applied on the statistics too.

Hi Stephane,
Pressing 's' for stats reveals the problem too. Looks like state is
leaking from the empty geode. This is certainly a bug, as to it's
possible cause I can't answer. I'm afraid I can only juggle so many
support items at one time so can't go chasing this bug right now.
