View Dependent Shadow techniques don't work with nested cameras. They work
with RTT Slave cameras though.

OK, you are right, but that is not my problem. I don't want the shadow
texture, which need the DEPTH_BUFFER. I want the "final" rendering in my
texture.
The basic graph looks like this:
ROOT
|
rtt_cam (the result has no shadows)
|
shadowedScene (with StandardShadowMap)
|
camera (is also a render to texture camera)
I hope it is better explanation of my problem.
Cheers
Martin

Maybe your problem is related to the fact that Shadow maps are usually
stored in DEPTH_BUFFER (not COLOR_BUFFER).

Subject: [osg-users] StandardShadowMap and Render To Texture
Hello,
Every day a new problem. :-)
Ok, so my Render To Texture works, but my shadows are not visible in the
texture (rendertarget).
My Settings:
rtt_cam->setRenderOrder(::osg::Camera::PRE_RENDER, 0);
rtt_cam->setRenderTargetImplementation( osg::Camera::FRAME_BUFFER_OBJECT
);
rtt_cam->attach(::osg::Camera::COLOR_BUFFER, rtt_tex, 0, 0);
Is the Problem the pre rendering? Because the standard shadow map has also
a
pre render camera. I am not sure which camera do the first rendering.
Or is it another Problem?
Cheers
Martin
