How to Generate Large Collections of NFTs with Metadata

Introduction: In this tutorial, we will learn how to generate large collections of NFTs with metadata included for Solana or Ethereum. Previously, figuring out this process might have been challenging, but with the right tools and guidance, it can be simplified. We will be using the hash lips art engine program, created by Hash Lips, to generate the NFTs efficiently. So, let's dive into the step-by-step process and start generating your NFTs.

Requirements for Generating NFTs: Before we begin, make sure you have the following requirements:

  1. Node.js: Download and install Node.js, which can be found on the official website (link provided).
  2. Visual Studio Code: Install Visual Studio Code, a powerful code editor available for Windows, Linux, and Mac.
  3. Git: Install Git if necessary. Follow the provided instructions for Mac, Linux, or Windows 10.

Downloading Node.js and Visual Studio Code: To get started, download Node.js from the official website as mentioned earlier. Make sure to select the LTS version compatible with your operating system. Once downloaded, proceed with the installation process.

Next, download Visual Studio Code by visiting the official website. Choose the version that corresponds to your operating system and install it. Visual Studio Code will be our primary code editor for this tutorial.

Installing Git: If you don't have Git already installed, you can follow the instructions provided in the link mentioned earlier to download and set it up based on your operating system. For Windows 10 users, a specific video tutorial link is provided for a hassle-free installation.

Cloning the GitHub Repository: After completing the necessary installations, visit the GitHub page provided by Hash Lips. Once on the page, click on the "Code" button and copy the link.

Open Visual Studio Code, which you have just installed, and go to "File" > "Open Folder." Select your desktop as the destination and choose the folder. After that, open the terminal by clicking "Terminal" > "New Terminal" within Visual Studio Code.

In the terminal window, type "git clone" followed by the copied link and hit enter. This will clone the GitHub repository to your local machine. Once the process is complete, go to "File" > "Open Folder" again, and navigate to your desktop. Open the "hash-lips-art-engine" folder to proceed.

Configuring the Metadata: In the "hash-lips-art-engine" folder, navigate to the "src" folder and open the "config.js" file. This file contains the configuration settings for your NFTs.

Within the file, you'll find a section for general metadata. Here, you can define the name prefix and description of your collection. The base URI will be the link to your files. If you are creating NFTs for Solana, you can also customize the symbol, seller fee basis points, and creators defines.

Scrolling down, you will come across layer configurations which determine the order and appearance of traits in the metadata. You can modify these layers based on your collection's requirements. Make sure to arrange them correctly to avoid any issues with the images.

Setting Up the Artwork: The next step involves creating folders and placing the artwork for each trait. In the "hash-lips-art-engine" folder, open the "layers" folder. Create folders with names identical to the variables from the layer configurations. Fill these folders with the corresponding trait images.

For each image, ensure the file names are accurate and align with the metadata. Additionally, add a rarity weight to each image by appending a number sign and a number out of a hundred. This determines the rarity of each trait, with higher numbers indicating higher chances of appearance.

Customizing the Traits: Within the "config.js" file, you have the flexibility to customize various settings for your NFT collection. Explore the width and height options to adjust the resolution of your images. You can also modify the background setting based on your requirements.

Consider the unique DNA variable, which determines the number of possibilities for your collection. Adjust this value accordingly, keeping in mind the number of traits and images you have. Additionally, ensure the correct network is selected (Ethereum or Solana).

Adjusting the Image Resolution: If you prefer high-resolution images, you can increase the width and height values in the "config.js" file. A higher resolution, such as 1000x1000, will result in crisper images. Feel free to experiment with different resolutions to achieve the desired outcome.

Generating the NFTs: Once you have configured all the necessary settings, it's time to generate your NFTs. To do this, open the terminal in Visual Studio Code by clicking "Terminal" > "New Terminal." In the terminal window, type "npm install" and hit enter. This command will install the required dependencies.

After the installation process is complete, enter "node index.js" in the terminal and hit enter. The script will start generating the NFT images based on the provided configurations.

Viewing the Generated Images: After the script finishes generating the images, a "build" folder will be created. Open the "build" folder and navigate to the "images" subfolder. Here, you will find all the generated NFT images.

Feel free to explore the images and marvel at the unique collection you have created. Additionally, check the "json" folder to ensure that the corresponding metadata files have been generated successfully.

Conclusion: Congratulations! You have successfully generated a large collection of NFTs with metadata included. This tutorial walked you through the step-by-step process using the hash lips art engine program. With your newfound knowledge, you can venture into the world of NFT creation and explore various platforms and marketplaces.

Remember to stay updated with the latest trends and developments in the NFT space. Consider sharing your creations on social media platforms like Twitter to gain visibility and connect with the NFT community. Thank you for following along, and best of luck with your NFT endeavors!

Q: Can I use the hash lips art engine for other blockchain networks? A: Currently, the hash lips art engine supports Solana and Ethereum. However, it can be modified to work with other blockchain networks as well.

Q: How can I ensure the rarity of certain traits in my NFT collection? A: By assigning rarity weights to each image in the "config.js" file, you can control the likelihood of specific traits appearing in your NFTs.

Q: Can I modify the metadata and traits after generating the NFTs? A: Yes, you can modify the metadata and traits by adjusting the configurations in the "config.js" file and re-running the script for generating NFTs.

Q: Are there any limitations on the number of images and traits in a collection? A: The hash lips art engine can handle a large number of images and traits. However, ensure that your system has enough resources to handle the generation process for larger collections.

Q: Can I collaborate with other artists to create NFT collections using this method? A: Yes, you can collaborate with other artists by sharing the "config.js" file and artwork folders to collectively generate NFTs with combined contributions.

Q: Are there any fees associated with generating NFTs using this method? A: The fees associated with generating NFTs depend on the blockchain network you choose (Solana or Ethereum) and the specific settings you configure for royalties and creator fees.
