Tutorial: stage and render an interior

You’ll build a bedroom from one prompt, light it, render it, then change it the way a client would. Every image on this page is a real result of these prompts in 3D-Agent.

First, connect 3D-Agent to Blender.

  1. Save a new file

    In Blender, open a new file and save it as bedroom.blend. A saved file gives your checkpoints a name.

  2. Build the room

    Name the style, the materials and every piece of furniture you want:

    Build a Parisian bedroom with herringbone parquet, tall windows with sheer curtains, a double bed, two nightstands and a reading chair. Realistic materials.

    In our run, 3D-Agent built a 5.4 × 4.8 m room with wall panel mouldings, two French windows, an oak herringbone floor with a border, a walnut bed with bedside lamps, a rug and a reading corner with a floor lamp. Every object gets a readable name, like Nightstand_01_Marble_Top, so you can refer to it in later prompts.

    To check a layout before you light it, ask for a view from above, like Show me the whole room from a high corner with the ceiling hidden.

  3. Frame the shot

    Add a camera in the doorway at eye level, looking at the bed, with a 35 mm lens.

    3D-Agent places the camera, makes it the active one and checks that the bed is in frame. In our run, it put the camera 1.65 m above the floor.

  4. Light it

    Light the room like a sunny morning: warm sunlight through the windows and soft fill light inside.

  5. Render

    Render the view from the camera.

    The render appears in the chat. A photoreal interior renders in Cycles, which can take several minutes.

  6. Iterate like a client

    Describe each change, then ask for a new render:

    • Move the bed against the left wall and render again.
    • Make it evening, with the bedside lamps on. Widen the shot so the bed, the windows and the reading chair are all in view, then render again.
    After the first change: the bed now stands against the left wall, seen from the side, with a nightstand and lamp in the foregroundAfter the first change: the bed now stands against the left wall, seen from the side, with a nightstand and lamp in the foreground

    The first change moves the bed and its nightstands together. The second one gives the evening shot at the top of this page.

    3D-Agent saves a checkpoint at the end of each turn. To go back to the morning version, open Checkpoints and restore it.
