The script will pause to allow you to choose your own colors,
patterns, texture or gradients using the materials palette,
so it could match your designer's needs.
The script is interactive and ends in layers,
so you can customize this element at your wishes.
The script has been tested in Psp 9 through X5
and requires NO OUTSIDE PLUG-IN.
