I created a tutorial at:
which shows how to create a checkerboard of any color in Blender 2.5 using texture nodes, and specifically Blender’s built-in checkerboard texture node. I did not use any images, only procedural textures and node transformations. This tutorial should also work in Blender 2.4x. I also wanted to demonstrate the new Blender 2.5 user interface. The tutorial is based on a mid-September pre-alpha release of Blender 2.5.
I welcome all comments.
