It's hard to guess at what is up with so little details. Which
ShadowTechniques have you tried?

SoftShadowMap isn't view dependent to get good quality results you
have to restrict the size of the shadow casting part of the scene.
Try the view dependent techniques such as
Hi community.
I am having some issues with shadowed scene. Imagine this scenario:
- terrain as a shadow receiver
- 1 moving model as shadow caster (the shadow looks good now)
- adding additional moving models (now the shadow of the first one still
looks great, but on all next models it is very

Hi Wyatt,
The fragmentShaderSource_debugHUD and
fragmentShaderSource_debugHUD_texcoord
shaders listed at the top of the cpp with the other two shaders
Ah, no those are only used
Hi Wyatt,
Oops... If I use the debug hud, then I need to use the
fragmentShaderSource_debugHUD and fragmentShaderSource_debugHUD_texcoord
shaders?
You're starting to go into the realm of questions you should be able to
answer yourself, using the source and trying things out. I can't help
and see
what they do.

Hi Wojtek,
I'm surprised the magic word to summon Wojtek (shadows) took so much
time this time! We've been discussing this for a few days now :-)

From the Common Questions of the osgShadow node kit.

Hi Wyatt,
Which shader is the basic shader, fragmentShaderSource_noBaseTexture or
fragmentShaderSource_withBaseTexture?
Depends on whether your object has a texture or not. Although now, since
texture lookups are so cheap these days, I would suggest you save
yourself some aggravation and

Thanks for your advices ! I've tested the uniform one by changing the shadow
technique shader and it works great.

Hi Serge,
Anyone
knows if there is a way to force an object to not receive the shadows ?
Even with a dirty method (reseting it's tex coords on the drawable or
something like that).
Wojtek is right (of course, having implemented some of the ShadowMap
techniques in OSG, he would know),
Hi Wojtek,
Thanks for helping out. Unfortunately I didn't have much time today
to further investigate the problem.
It does not sound like easy one. Are you sure that ATI bug only affects
texture application ? Maybe render to texture is also flipped somehow. I
assume you have modified

I am afraid you are on your own - I will not be able to help much. Shadow
