Hi Nick,
ok I did have a look at the osgPrerenderCubeMap code and at you thread about 
mixing a static 2D texture and a dynamic cube map into a shader. btw your 
version with 

Code:
{ 
osg::Uniform* u = new osg::Uniform(osg::Uniform::SAMPLER_CUBE,"cubeMapUnit"); 
u->set(unit);   
node->getOrCreateStateSet()->addUniform( u ); 
} 


 works well for me

I tried this sample with my own camera (Y up) and that works well too.
I want to use this sample in a more general case (dynamic reflection on water 
for example) . I tried to use the bottom plane as the reflector but the 
reflection is now awfull... Did you work on it ? Can you confirm ?

Thank you
Sebastien
