Two ways to create.
Render mode
Start with your model view or an imported image. Use a prompt and optional references to explore materials, lighting and atmosphere, with your source view guiding the geometry and camera.
Speculative mode
Start with an idea. Describe what you want to create and add reference images if you like. Explore new architectural concepts without a 3D model or a fixed camera view.
Take either result further with image editing, sketch-guided changes and Magnific upscaling.
