texture - a valid texture handle
mode - the rendering mode of the cubemap texture: 1: Specular (default) 2: Diffuse 3: Refraction |
|
Set the rendering mode of a cubemap texture.
The available rendering modes are as follows: 1: Specular (default). Use this to give your cubemapped objects a shiny effect. 2: Diffuse. Use this to give your cubemapped objects a non-shiny, realistic lighting effect. 3: Refraction. Good for 'cloak'-style effects. See also: CreateTexture, LoadTexture, SetCubeFace. |
