AI Render - Stable Diffusion in Blender is an add-on that generates an AI image from a text prompt and your scene. Setup takes under a minute: create a free DreamStudio account, from the makers of Stable Diffusion, and images render in the cloud with no code to run or install. If you would rather not create an account anywhere, you can install Stable Diffusion locally through the Automatic1111 Stable Diffusion Web UI.
Beyond stills, the add-on renders animations using all of Blender's animation tools, and lets you animate Stable Diffusion settings and even the prompt text. That same animation workflow doubles as batch processing, so you can try many different settings or prompts in one pass. It runs on Windows, Mac and Linux, and works with both the Cycles and Eevee render engines.
Released under the MIT license and listed here as free, AI Render sits at rank 214 in the superhive library. A demo video is available, and the developer's Github wiki covers prompt engineering and frequently asked questions.
