I take a floor object and a Backround. Both of them get a compositing tag.
I use the parameter Compositing backround, so when i put a simple material (just a color)
to both of them, i get a nice smooth backround from top to bottom.
Here comes the problem.
When i give this material a simple reflection, i cant get the smoothness and i can always see the line between the floor and the 'sky', meaning the horizon.
I just need a clear backround with a reflection for the floor.
I want to solve this another way and not with a curved surface behind the objects.
There must be a way.
