You can set parameters of the texture and add this to the ToolPalette in your personal gallery.
In the ToolPalette, click the category of texture you are interested in, then click one of the texture icons to the right.
Now, click the Parameters button on the ToolPalette.
In the Parameters dialog box, select the Adjustment tab and use the slider bars to adjust the parameters.
Now generate the texture. Apply the texture to the image. Modify the parameters and repeat generate if necessary. You can also click the Variation button to make a new variant of the texture.
After a little while (the rightmost portion of the status bar shows the progress), the rendered texture will be displayed.
You can save and add this texture, or your custom settings, to the ToolPalette for future use.
Now, enter a name for this texture setting that will remind you of what it does or when to use it.
