I am using the LISPSM shadow technique. It works great for the most of the

Is this a know issue or am I doing something wrong?

Hi Frederik,
Default vertex shader ( see line 278 of osgShadow::StandardShadowMap)
passes specular component through gl_SecondaryColor. If you expect specular
to be mixed with diffuse and ambient on primary gl_Color then you may need
to adjust the shaders. Use setMainVertexShader /

Hi Mike,
position-setScale(osg::Vec3(0.01,0.01,0.01));
When you use scale in a Transform, the geometry's normals also get
scaled. The normals are used to compute lighting, so it's normal
(geez, bad pun) that lighting is wrong.
You just need to tell OpenGL to rescale normals:
Hi Paul,
Why do I have multiple SceneViews?
There are always two SceneViews if you're using multithreading - they're

both, or a separate instance of your CullVisitor for each instance.

What are some of the legitimate reasons that OpenGL may be unable to

memory?

Hi there,
I'm doing something very similar - OSG hosted in .NET. The way I've done
this is I have my render thread running in a loop and instead of rendering
continuously, I have a StackRenderArgs hosted in the OSG .NET control.
Then if I want to render, I push a RenderArgs onto the stack.
Yes, just thinks like Maximise, Minimise, Resize. I also rendered on
Activate in case the form lost and regained focus.
There's no problems integrating OSG with .NET Windows Forms from what I can
see.

Hi Paul,
I think there is a better way to set your own visitor, maybe doing:
osgUtil::CullVisitor::prototype()=new MyVisitor();
if you do this before realize() (or run()), then the viewer uses the
