The Env Sky texture is an environment map that generates
images of a planetary atmosphere as seen from the surface of a
planet.
Sky attributes let you control the composition of the atmosphere
and the cloud layer. If no floor is specified, the environment
below the horizon is a vertical mirror reflection of the
environment above the horizon. If you specify a floor, you can set
it to a color or use a texture map. If a floor is specified and the
camera point-of-view drops below that floor, then the sky will turn
red as a warning. You can use the Env Sky texture as a reflection
map, by connecting its Out Color attribute to the Reflected Color
attribute of an specular shader, such as Blinn or PhongE. You can
also use the Env Sky texture as a background, by connecting it to
an image plane. For best results, scale the sky so it is in
proportion to the half-height of the image plane. Aside from the
attributes listed here, Env Sky inherits additional attributes from
TextureEnv. In the table below,
important attributes have their names listed in bold in the
description column.
