This rug has thirteen textures on board, allowing it to coordinate with all of the Louis furniture line. Just click on the rug to access the texture control.
If you like to keep your script count down, or not have the menu popping up every time you click...
Once you have found your favorite texture, you can delete the script from the contents of the rug, or disable it.
The rugs are copy and mod, so if you ever want to change it again simply rez a new one from inventory.
