Hasta La Motion!

i just tried the modeler node in 6.2v4
i was able to create a plane in the modeler as expected and all was ok.
later i tried again and now i am not able to use the modeler anymore o.O

after i connect it to my camera and the backplate like needed and view the modeler in the viewer
– the viewer always swtches to 3D display.
– if i change to 2D the image is plain black. ( i could create polygons there but that makes no sense)

any ideas? reboot and other user and other comter even was checked without any success. nukeX license is available for sure.

cheers

p.s.: the attached image should create an image at least; right? (only for showing the problem; of course i try with my real sequence and the tracked camera)
