# How to Add 1/1 NFTs to Your Generative Art Collection

A **1/1**, **1 of 1**, or **one of one**, is an NFT that has been issued as a single, unique edition. One of ones are seen as more scarce and therefore more valuable, because only one person can own them at a time.

We will guide you through each step once your generative art collection is ready, as shown in [this tutorial](/create-and-deploy-nft-collection/generative-art-collection.md).

This approach is ideal when you want to include one-of-one artworks *within* a larger generative collection. If instead your entire collection is made up exclusively of 1/1 pieces, it may make more sense to use the **Drop** tool — as explained in [this tutorial](/create-and-deploy-nft-collection/drops-collection.md).

#### **Step 1: Create a New Layer for Your 1/1 NFTs**

To begin, create a new layer and name it **"1/1"**. Set its **Likelihood to 0%**, which ensures these traits won’t be randomly selected during the generation process.\
Now, upload your special and complete artworks — these will be your unique 1/1 pieces. In this example, we’ve uploaded two: **"Vampire Bot"** and **"Unicorn Bot"**.

#### **Step 2: Set 0% Rarity for Each Trait**

For each image you uploaded to the **1/1** layer, manually set the **rarity to 0%**.\
Once all 1/1 images have 0% rarity, you can go ahead and generate your collection. These traits will be excluded from the generative output — meaning they won’t be randomly assigned — and will instead be manually applied in the next step.

#### **Step 3: Assign 1/1 Traits to Specific Token IDs**

After generating the collection, navigate to the **"Result"** tab.\
Here, you can manually assign your 1/1 NFTs to specific token IDs. Click on the token you want to modify and enter the **editor**.\
In the editor, you can give this NFT a **custom title and description**. Then, set all traits to **None**, except the one from the **"1/1"** layer — choose the correct unique trait (e.g., "Vampire Bot").

#### **Step 4: Repeat the Process for Other 1/1s**

Here’s an example using the other special 1/1 artwork, **"Unicorn Bot"**.\
Repeat the same process: select the token, edit its metadata, and assign the correct 1/1 trait. You can do this for as many unique images as you like — whether it's two, twenty, or hundreds.
