EasyTextures comes with two scripts for your object, two for your HUD, and an item that gives you your secure key.

Item Goes in What it does
.config Your object Holds your object's name, your UUID and the object's options.
Kynno - EasyTextures Your object Applies the texture sets the HUD sends.
.config HUD Your HUD Holds your texture sets: what each button changes.
Kynno - EasyTextures HUD Your HUD Reads your texture sets, and sends them to your object when a button is clicked.
Kynno - User Secure Key (wear/add) Worn by you Gives you your secure key, which the .config HUD needs.

The two main scripts carry their version in their name, like Kynno - EasyTextures v3.0.

How it works

You write texture sets in the .config HUD: named lists of changes, like "put this texture on faces 1 and 2 of this prim". Each button of your HUD applies one texture set. When a customer clicks it, the HUD sends the set to their object, and the object's script applies it.

The HUD and the object find each other through the object name you write in both .config scripts, so a HUD only ever changes the object it was made for.

The .config scripts are only needed while you set things up. Build your HUD explains which one to keep before you release your product.

Next, Set up your object.
