# horizon mapping in cycles

I am rendering a scene using cycle and I have set up a background with a Sky texture. Now I want to adjust the height of the horizon. I tried to use a Mapping node but what it does is changing the background in a solid color (which varies depending on the Z value).

This didn't work because the Texture Coordinates node wasnt added. You should plug one of its output sockets (e.g. Generated or Object) into the Vector input socket of the Mapping node (this is a common approach if texturing anything in Cycles. Otherwise, in Cycles, texture won't appear on the mesh, just solid base color).
(I changed Location value to 0.3 here).
