Unity Integration v1.3.0 2 | A basic but functional Unity Editor Component for image generation using Stable Diffusion Automatic 1111 [webui](https://github.com/AUTOMATIC1111/stable-diffusion-webui) from within the Unity Editor. 3 | [![Watch the video](screenshot.png)](https://youtu.be/8gf5GPzhgk8) 4 | 5 | 6 | # Token of Appreciation 7 | If you like it, feel free to Buy me a Coffee (https://www.buymeacoffee.com/dobrado76) 8 | 9 | Cheers! 10 | 11 | # Overview 12 | Simple server configuration with StableDiffusionConfiguration component and SDSettings ScriptableObject assets. 13 | ![](SDSettings.png) 14 | ![](SDConfiguration.png) 15 | 16 | Easy Text-to-Image generation for 3D models: 17 | ![](SDMaterial.png) 18 | 19 | Straightforward Text-to-Image generation for UI elements: 20 | ![](SDImage.png) 21 | 22 | 23 | # Features 24 | - Text-to-Image generation with Prompt and Negative prompt for: 25 | a) texturing 3D models having a MeshRenderer component with tiling option and generation of Normal/Bump maps, 26 | b) UI component having a Image or RawImage component (Canvas, Panel, Image, Button, etc.) 27 | - Image-to-Image generation with Prompt and Negative prompt for: 28 | a) UI component having a Image or RawImage component (Canvas, Panel, Image, Button, etc.) 29 | - Editor only components for scene/level design (no runtime dependencies to Stable Diffusion) 30 | - Image generation using any Stable Diffusion models available in the server model folder 31 | - Standard parameters control over image generation (Prompt and Negative Prompt, Sampler, Nb. of Steps, CFG Scale, Image dimension and Seed) 32 | - All images saved in the Assets folder for persistent storage and reference 33 | - Can run from a local Stable Diffusion server, which requires no API key, or from an online surver such as a Runpod Virtual instance. 34 | 35 | 36 | # Dependencies and requirements 37 | This Unity Editor tool requires access to a Stable Diffusion Automatic 1111 server. Installation or usage of such server is outside the scope of this documentation. 38 | Please refer to the SD A111 WebUI repo: https://github.com/AUTOMATIC1111/stable-diffusion-webui 39 | 40 | 41 | # Getting Started 42 | 1. Install [Stable Diffusion WebUI Automatic 1111](https://github.com/AUTOMATIC1111/stable-diffusion-webui). 43 | 2. Launch [Stable DIffusion WebUI Automatic 1111](https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/API) with the '--api' argument in the command line define in the "webui-user.bat" command file, in the root folder of your SD server. 44 | Without Authentication: 45 | set COMMANDLINE_ARGS= --api 46 | ; Or with Authentication: 47 | set COMMANDLINE_ARGS=--listen --api --api-auth YOUR_USERNAME:YOUR_PASSWORD --cors-allow-origins=* 48 | 49 | 3. Either, Download the stable-diffusion-unity-integration repository, for example by running `git clone https://github.com/dobrado76/Stable-Diffusion-Unity-Integration.git`. Then, Open the stable-diffusion-unity-integration project in Unity.then open the Demo Scene provided in the package found in `StableDiffusionIntegration/Scenes/DemoScene.unity`. 50 | 51 | Or; 52 | 53 | 3. Create and open a new Unity project for Built-in Pipeline, download and import the stable-diffusion-unity-integration.unitypackage file into the project (https://github.com/dobrado76/Stable-Diffusion-Unity-Integration/blob/main/Stable-Diffusion-Unity-Integration.unitypackage). By starting from a new project and importing the package, none of the demo pre-generated images will be available in the Asset folder but the project should work as-is, since the textures and images are embedded in the Unity project. 54 | 55 | 4. Open the Demo Scene provided in the package found in `StableDiffusionIntegration/Scenes/DemoScene.unity`. There is a version with Post-Processing (you need to install the Post-Processing package, you will need to re-open the scene after installing the package) and a version without Post-Processing. 56 | 57 | 5. Select the StableDiffusionConfiguration component and make sure the selected setting point to the correct URL and Port (default: http://127.0.0.1:7860/). 58 | 6. Click on the `List Model` button to get the list of all available models from your local Stable Diffusion server. 59 | 60 | ![](SDListModels.png) 61 | 62 | 7. Select any existing GameObject with a MeshRenderer (or that contains at least one child with a MeshRenderer) or an Image (or RawImage) and click Generate from the StableDiffusionText2Material, StableDiffusionText2Image or StableDiffusionImage2Image component to generate a new image using the specified parameters. 63 | 64 | ![](SDMaterial.png) 65 | 66 | 8. If any error occured, it should be catched by a try/catch and the exception displayed in the Unity Console. 67 | 68 | - The StableDiffusionMaterial component requires to be added to a GameObject that has a MeshRenderer (if apply recursively is not used) or have at least one children GameObject (if apply recursively is used). 69 | - The StableDiffusionImage component requires to be added to a UI GameObject (in a Canvas hierachy) that has an Image or RawImage component. 70 | 71 | 72 | # Limitations 73 | Be aware of a few limitations: 74 | - This repo has been testing only in some versions of Unity (2019, 2020, 2021 and Unity 6). It is believed that it has only basic low level Unity dependencies and should work in any versions. 75 | - The components for generating materials are designed for the Built-in render pipeline and Universal Render Pipeline (URP) only. It may be easy to get it to work for HDRP but no effort has been done in that regard.
