I also have a Camera-problem, so I write it here, I dont want to make a new thread.
I had a landscape, I call it "File001" an was satisfied with the view, so I saved the camera-node as clipfile. Then I saved the file again, named File002.
I made some different camera-settings and worked on the file two days, then at least I wanted the same settings as for the camera in File001.
I imported the clipfile, chained the node to the render-nodes and deleted the origin camera-node of File002. Now I should have the view of File001, shouldn't I?
But the view of File002 didn't change, what went wrong?
