Sky

The Sky is a hollow box that surrounds your level. Faces to which you assign the “Sky” attribute (see Face Attributes Dialog) are displayed with sky textures and are animated to simulate a rotating sky. The Sky Options Page lets you define the textures to be used for each of the six sky faces.

Each face has a checkbox and a drop-down combo box. To enable a particular sky face, make sure its checkbox is checked. Then, select the texture to be applied to that face from its drop-down combo box.

You may also change the rotation axis and speed of the sky.
