I am trying to mask one object in an animation. At the moment I am using a green cube to mask it and using the Node-Editor to bring the picture back to together.
I achieved to mask the object with this technique but now I’m confused how I can get rid of the part of the shadow/reflection from the object that is behind the mask.
Attached is a simple scene, where I am trying to receive this.
There is something I really don’t understand. I have 3 different RenderLayer.
The ground is on an different Layer than all the other objects and the material of the ground has a mirror effect.
So to render all the RenderLayer I have to select all the Layer and so I get the shadows and the reflection on the ground of the objects.
But if I use the Layer of the ground by itself no shadow and reflaction appear. So why do they appear in the RenderLayer, because there I selected only the Layer with the ground. I guess it should Render it without the shadows and the reflection, shouldn’t it?
Any help would be very nice…
