I have a question which I think could be categorized as a “masking” question, but I’m not sure, I’m so new.
I’m working on this “2-1/2D”-Animation, the camera is not moving. What I want to do can most easily explained by refering to this really simple example: Imagine a picture frame in the scene (most distant from camera), the object portrayed in the picture (simple sphere, closer to camera than frame) should appear moving out of the picture frame and be gone/invisible. How do I go about this? Do I have to look into the msking manual? What would get me started?
What I tried so far is to create an invisible object ( on the edge of my picture frame (and closest to the camera) so that the sphere is hidden behind that invisible object as soon as it exits the border of the picture frame. Method described here: http://blender.stackexchange.com/questions/33301/invisible-object-that-hides-other-objects-as-a-mask
But then the invisible objects masks out ALL objects that are positioned behind it, including the part of the picture frame that it covers up (and background objects i didn’t mention yet) which is not what I want.
I tried moving the “masking” object and the sphere to a seperate layer but that didn’t help…
I am deeply out of ideas, blender is just so complex… Thanks a lot really for any thoughts on how to go about this!
