Introduction

Welcome to this tutorial on how to Create a NFT character generator using Geometry Nodes in Blender. In this tutorial, You will learn step-by-step instructions on how to organize and create a generator that can generate unique NFT characters by frame. By the end of this tutorial, you will be able to render your own NFT characters and customize them according to your preferences.

Getting Started

Before we dive into the creation process, make sure you have downloaded the final project file from my Patreon page. This project file includes all the necessary assets and resources needed to follow along with this tutorial.

Organizing the Generator

To start creating the NFT generator, we first need to organize our character and its attributes. If you already have a character model, great! If not, you can download one or create your own. Make sure your character has attributes such as the eyes, glasses, body, hair, etc.

To join multiple objects together, ensure there are no modifiers applied to the objects. If there is a mirror modifier, it will be applied to all objects when joined. You can keep a subdivision surface modifier on the objects, but if not needed, Apply it. Once you have edited each item and applied the modifiers, select all objects and press Ctrl J to join them.

Next, apply the location of each item. Select all the items, press Ctrl A, and choose Location. This will ensure the origin point of each item is at the center.

Now, it's time to organize the items into collections Based on their attributes. For example, select all the clothes items and move them to a new collection named "clothes." Repeat this process for all other attributes like bodies, hairs, etc.

To determine the rarity of each item, access the collections from the Outliner. For example, you can make the normal shirt a common item by duplicating it. This will increase the chance of it appearing in the generated NFTs.

Creating the NFT Generator

In the Geometry Nodes workspace, add a plane in the 3D viewport. Enter edit mode, select everything, and merge all vertices at the center. This empty item will serve as our NFT generator. Rename it accordingly.

In the Geometry Nodes Editor, click on the "New" button to create a new geometry nodes setup. Make sure you have enabled the Note Triangular add-on under Edit > Preferences > Add-ons.

Add a Point Instance node and connect the geometry to the geometry input of the Group Output node. This will ensure the points are at the center.

To use our collections as instances, drag and drop one of the collections from the Outliner to the Geometry Nodes Editor. Connect it to the Instance input and check the "Separate Children" and "Pick Instance" boxes. This will display all the objects in the collection. Add an Integer node and connect it to the Instance Index. By changing the integer value, you can change the item's index and see other objects in the collection.

Repeat this process for all the collections. Hide the unused inputs by selecting the Instance on Points node and pressing Ctrl H. Press Ctrl H again to unhide them.

After connecting all the collections, add a Join Geometry node and join every instance on points together.

To add variation to the generator, combine the noodles of these nodes into a single input by holding Shift and right-clicking and dragging. Add a Random Value node and change its Type to Integer. Set a high number like 1000 for the max value and connect it to the inputs. This will allow you to generate different NFT characters by playing with the seed output of the Random Value node.

Finally, add a Scene Time node and connect the frame input to the C input. This will allow you to generate the NFT characters by frame.

Lighting and Rendering

Once you have created the NFT generator, it's time to set up the lighting and rendering. Customize the frame range in the Output Properties panel to determine the number of NFTs you want to generate. Choose a folder to render your NFTs and click on Render > Render Animation. The rendering process may take some time, depending on the number of NFTs.

Conclusion

Congratulations! You have successfully created a NFT character generator using Geometry Nodes in Blender. By following this tutorial, you have learned how to organize and generate unique NFT characters based on different attributes. Feel free to experiment with different variations and settings to create your own personalized NFTs. Happy generating!
