Consider the following setup:
- a camera
- an object in front of the camera
- a solid/non-transparant wall behind the object
- a light_source behind the wall
Now, for some arcane reason, I want the light_source to shine on the
object while the wall remains visible to the camera.
I first thought of a light_group {} with object and light_source in it,
but the wall still blocks the light.
Any smart idea? I am sure it should be possible and I have the nagging
feeling that it has been done before.
