The World Background

The simplest use of the World Buttons is to provide a nice gradient background for images.

The background buttons (Figure 2) allow you to define the colour at the horizon (HoR, HoG, HoB buttons) and the colour at the zenith (ZeR, ZeG, ZeB buttons).

The World Buttons also provide some texture buttons. Their basic usage is analogous to Materials textures, except for a couple of differences (Figure 3):
