Hi Carsten, concerning my current knowledge of OpenSG 2.0, this seems to be out of scope. For the moment, I will reduce the size of the plane, and try to come up with a work-around.
reading about shadows on the web-site and in the tutorials, i found different types of smoothing algorithms and parameters for them (one of the reasons i chose opens). but it seems that in OpenSG 2.0 things have changed. I cannot find a way to choose the smoothing algorithm and its parameters. The examples do not include code-snipplets.
