As an alternative to using the Texture Channels, Blender includes a node-based texture generation system which enables you to create textures by combining colors, patterns and other textures in much the same way that you combine Material Nodes.
The purpose of this video is both to introduce texture nodes in Blender 2.5 and to familiarize you with the new Blender 2.5 user interface, particularly the Node Editor. We are going to create a checkerboard, which you can customize to any colors for the squares, without using any images. We will create a checkerboard texture in the Node Editor, built from Blender 2.5's built in checkerboard texture node.
