Hi Gerrit, Thank you very much for your help. Pressing "g" I got the example working and things got more clear.
Sadly I'm quite new to the "Override" concept of OpenSG2.0. Even If I think to have understood, is there any doc about this? If I've correctly understood, the TextureChunk is added to all child of the "CubeMapGenerator" Node, isn't it? And the scene rendered into the cubemap can be provided with the "setRoot()" method of the CubeMapGenerator, right? For some reasons I want to see only the CubeMap Texture and not the rest of the scene. Referring to the example, I want to see only the mirrored sphere and not the objects around it. How can I achieve that? I tried by giving the viewport only the CubeMapGenerator node and passing the rest of the scene to the CubeMapGenerator through the setRoot method, but with no luck. Any idea on this?
