Unity Library

The InventAI Unity Library lets you generate 3D models and image assets directly in Unity using AI.

Features

• Generate 3D models from text prompts
• Choose between different models
• Generate image assets and textures
• Use art presets (universe, art style, genre, etc.)
• Create animation sprites from existing images
• Modify existing assets to change your game's look and feel in minutes

Installation

InventAI Unity Library is a Unity package that can be installed very easily just like any other Unity package. It is available for Windows, Mac and Linux.

1. Download the latest .unitypackage from the InventAI Unity Library releases page.
2. Open your Unity project.
3. Go to Assets > Import Package > Custom Package... and select the downloaded .unitypackage file.
4. Click Import to add InventAI to your project.
5. Start using InventAI features in your Unity project!

Generating image assets

Requirements

• Unity 2021.3 or newer is recommended.
• You might need to install Test Framework and Editor Coroutines packages on Unity if you don't have them already.

Setup

• Start by configuring InventAI in your project settings, by choosing the correct API key and model.
• You can also create custom prompts and art styles, and save them for future use.

Usage examples

Generating 3D models

Requirements

• Have Hunyuan3D-2 installed locally or have a public API
• Install UniGLTF plugin on Unity to use 3D .glb files
• You might need to install Test Framework package on Unity for the UniGLTF plugin to function properly.

Note: Hunyuan3D doesn't run locally on Mac, so you'll need a public API to be able to generate 3D models using our tool.

Setup

Once you've imported the library into Unity, you can use the custom editor interface to send prompts to Hunyuan3D for model generation. The editor includes the following fields:

• Text Prompt: Enter a detailed description of the object you want to generate. Hunyuan3D supports generating one object at a time. Keep in mind that more complex prompts may increase generation time.
• API URL: The endpoint to which Unity will send the request.
• API Key: Leave this empty if you're using a local instance of the model.
• Filename: Specify the name for the generated model file.
• Save Path: Define the folder where the model will be saved. For example, setting this to 3D models will create or use a folder at Assets/3D models in your Unity project.

The generated .glb file will be saved inside the folder you specified in the Save Path.
You can now use UniGLTF to import and use this model directly within your Unity scene.
