Blender's world environment sky looks flat Has anyone addressed the Blender environment sky horizon? It occurs to me so many landscapes are childish refrigerator art (mine certainly included) because Blender's sky horizon is at zero degrees off the X,Y axis no matter what the camera's Z location.

I would say there needs to be a 'degrees off tangent.' If looking directly straight out is along a tangent plane, then the horizon of a sphere would fall some degrees away from that regardless of distance or diameter of the sphere. The higher you were, the greater the degrees. This might allow Blender artists to submit better landscapes?
You can adjust the coordinates of the Environment texture to manipulate the 'centreline' of the environment. This can be achieved with the following nodes :



Adjust the Mapping node to skew the coordinates in a specific direction. The Normalize node ensures the result is still a valid Normal for the environment texture.

Obviously there are limitations to this since the environment is effectively projected onto an infinite sphere - adjusting too far will noticeably reduce one half of the environment into an ever decreasing circle while stretching out the opposite side.
