Blend
The Blend texture generates a smoothly interpolated progression. This is one of the most frequently used procedural textures. You can use blend textures to blend other textures together (with Stencil), or to create nice effects (especially with the Mapping: Normal trick).
Note
Remember that if you use a ramp to create a custom blending, you may have to use No RGB, if the Mapping value needs an intensity input.
