AI Render is an add-on that integrates Stable Diffusion directly into Blender, allowing you to generate images based on a text prompt and your 3D scene. It supports cloud rendering through a DreamStudio account or local rendering using the Automatic1111 Stable Diffusion Web UI. The tool includes animation capabilities, enabling the automation of Stable Diffusion settings and text prompts across multiple frames. Users can also utilize the animation framework for batch processing to efficiently test various prompt and parameter combinations.
