How do I use reference images?

References show the model a material, a piece of furniture, an object or an atmosphere you want to see in the render. In Nodes, connect several images to the Generator — the first is the base and the rest are references — and give each one its type: material, furniture, element, scene, style… In Canvas AI, press “Add Reference” on the engine or pick a piece from the furniture catalog; in AI Chat, attach more than one image: the first is the base.

Each model uses a maximum number of images, counting the base, and any extra ones aren't used; GPT Image and Seedream 5 add 5 tokens for each extra image. The details are in “Editing models”.
