Hi.
Unfortunately, no. If it becomes the bottleneck, I'll definitely have a
look at it. But for now it works fine.

Hi Michael,

Unfortunately this will render the geometry three times.
First shadow map depth pass, Second to create the screenspace shadow 
texture and for the RTT again.

Any idea how to prevent the second pass and move it to some later stage?

Cheers
Sebastian

Hi.
I have the sample that worked just fine:

Hi all.

Has anyone tested the EffectCompositor together with osgShadows?

My problem is, that as soon as I add a shadowed scene as a child
of an EffectCompositor, the shadows becomes all wrong.
It looks like the shadow light sources follows the camera, sort of.

The attached effect (asd.xml) is just a pass-through effect.

Other than this, is there any other good way of defining
post-render effects in OSG these days?
osgPPU seems to have fallen into sleep, and I cannot see any other
good way of constructing this.
The EffectCompositor really looks great. But...shadows does not work.

Anyone with insight into this?

Well you are using a custom shader for the shadows and not the one used
internally in osg. Sothere might still be an issue with the combination
of EffectCompositor and OsgShadow.
