Hello Carsten,

thanks for the fast reply.

The number of materials is manageable, so it shouldn`t be a problem to 
assign a chunk to all of them.
But I don`t understand how it is possible to use the comfortable 
ShearedStereoCameraDecorator with my setup. As far as I understand, I have 
to assign a single camera to a single viewport and they are combined by a 
single call of SimpleSceneManagers redraw-function.
But in my case, I have to render the views one after another into the 
stencil-buffer by hand.

Best regards,
Rene
