Hi OpenSG-Users,
I want to setup the Tutorial - "Without Simple Scene Manager" from
OpenSG 1.8 with OpenSG 2.0, but it doesn't work.
The Backgrounds and Viewports seem to be, what I expect it to be, but
the Torus is missing in the scene.
Perhaps someone of you guys could tell me, what I missed.
thanks,
Constantin
PS: I just want the basic function, not the Screenshot-functionality.
