Hi Robert,
Thank you for all those explanation, it's all make sense now. You're
perfectly right when you say that I want manage my own lighting, that's why
I told the viewer to bet set up with NO_LIGHT. I'm gonna update my svn
version from OSG and try the fix in my own application.
Kind regards,

Hi Robert,
sorry to bother you again but it seems that the fix you've merged works for
the previous osgLight.cpp file I have sent to you but not for my
application.
So I decided to write another osgLight.cpp (attached) file wich is more like
my application lighting setup.
The bug is appearring
Hi Alexandre,
Curious. If I comment out the
view-setLightingMode(osg::View::NO_LIGHT); everything works as your
scene graph sets out. But with no viewer light set it doesn't work...
I suspect much of these problems come about because to get osgViewer
up and running more quickly I choose to
Hi Robert,
*If I comment out the view-setLightingMode(osg::View::NO_LIGHT); everything
works as your scene graph sets out
*That's what I do to make it works for the time being.
*In your own code just don't bother the setting anything in view w.r.t
lighting, just set it up in your own scene
Hi Alexandre,
I've now figured out what is going wrong, and just with GL_LIGHTING
management not being correct in SceneView and in your own app, the
same also applies to GL_LIGHT0 which you wasn't been managed correctly
in SceneView, and not correctly in your osglight.cpp.
I fixed the problem in
Hi Alexande,
FYI, I'm now looking at this issue. It does look like a bug, I
haven't characterised the problem yet though...

Hi Alexandre,
I have some intial finding w.r.t the lighting turning off in the scene
when you use:
view-setLightingMode(osg::View::NO_LIGHT);
The reason why this unlights the scene, is because the scene graph
setup lacks any enabling of GL_LIGHTING, and it was only visible
because when

Hi osg-users,
I recently have found something weird about adding slave camera to
osgViewer::View when managing my own lightning.
I'm using OSG SVN version.

HI Alexandre,
I can't find the code you are referring to in the osglight.cpp you provided.
I'm afraid I really don't understand what you are trying to achieve,
and what is happening that is wrong. Given this there is nothing I
can do till you provide a clear example code and a better
Hi Robert,
I'm sorry If my explanation wasn't clear enough but it seems to be to be a
serious issue so I will take more time to make myself clear.
In the file osgLight.cpp previously attached there is a piece of code in
main function at line 397 to 400 :
HI Alexandre,
I read your explanation but am still am confused. Could you modify
the code so that you use a command line argument to add/remove the
code this will make it easy to test the two configuration without
recompile.
As for it being a serious issue, well it could well still be an

Thanks for the updated example and screenshot, this makes it much
clearer. I'm fixing another bug right now, but once that is complete
I'll have another look at this example.
