- A mapping channel holds a set of texture-mapping parameters. Each mapping channel is identified by a number. An object can have any number of channels and therefore can hold any number of texture mapping types.
- Textures in materials can be assigned a channel number. When the textures are applied to an object, the texture is applied using the matching channel number on the object. Texture channels default to channel 1.
- If an object has no applied texture mapping, uv surface mapping is used to map the texture.
