Creating the Initial Gradient|
Initially, create a new gradient with plenty of knots. Then simply capture the gradient from an image. Remember, you can view how the captured gradient looks using one of the in-built texture generators. The two handles for the gradient sample in the image window can be adjusted with instant feedback allowing the gradient capture to be fine-tuned. Of coarse, you can always just load a gradient from any Lightwave object, preset or surface file or simply make one up.
Import the Gradient into Lightwave|
Then simply export the resultant gradient as a Lightwave surface file and load it directly in the surface editor. It is then, simply a matter of attaching the gradient layer to any procedural texture just like any other surface.
Create the Final Surface and Render|
The gradient can be used for not only color but can be copied and used where ever a gradient is required. In this case the same gradient was copied to the specularity channel so that only the metal was shining. So that's a quick, peeling paint metal texture in around a minute!
