In the materials lab click on the top right round button with the down arrow while holding the "Shift" key on the keyboard. The Textures Window will open instead of just the names for the textures. Open the texture library you want to dump the texture into. I picked Sand for this one. Click "Add" at the bottom of the textures window. The Add Preset Window opens. Type a name (I picked Rusty) and description and click the check mark. You can now click on the B dot in the Materials lab for an atribute like specularity and load rusty from the sand menu. I did this so I could turn off the bump from component 1 and just apply specularity to the color.
