Ok... so I did what you suggested mostly... I took the osgshadow example,
add my geometry and it worked. I added another shader on the root node of
the scenegraph, because in my app, I do that. I took the shaders from
ShadowMap.cpp and put them into vert/frag files and loaded them into their
this screenshot directly to
my address.

I think I am about to get this straightened out...
I have implemented the LiSPPSM shadow code in my app. My scene consists of
two vehicles and a terrain. If I don't add the terrain, I can see the
shadows on the base test geometry and it looks pretty good. The base
geometry just happens to be

1. Is there a way I can query the number of texture units available on my

Did you check the debugHUD (with LISPSM it's as easy as
shadowTechnique-setDebugDraw(true) )? Does it show something that
looks valid?
I am not sure... With the debugHUD in the ShadowMap example, there was just
a window which appeared to display the shadow map in gray-scale, but in the
LISPSM
I have taken the code I think I need from the osgShadow example and tried to
add shadows to my existing application.The problem is that the shadow
map displayed in the debug window is just a gray-ish circle centered on a
white-ish background, nothing at all what I expected and no details that

Getting closer to having this working like I think it should, but I have
noticed something.
When I have one or two objects, say the size of a car, or truck, only. The
shadow map looks correct. But when I add my terrain which is approximately x
= 5100 by y = 5100, I no longer see the car/truck
My shadow map is looking mostly correct now after making changes to light
type, position etc. However shadows are not appearing in the final
rendering. The app I am trying to add shadow mapping to uses textures bound
to tex units 0-3. I noticed in the ShadowMap class there were methods for
