Go to: Attributes.

TextureEnv is the base node from which all the 3d environment texture nodes derive. Here you will find all the attributes that are common to all 3d environment textures.

Environment textures are used as a cheap way to simulate the reflections you can get using RayTracing. Connect the Out Color attribute of the Environment texture to the Reflected Color attribute of any specular shader, such as Phong or Blinn. The shader will then appear to reflect the environment texture. In the table below, important attributes have their names shown in bold in the description column.
