Realtime AI image generation is live in Fenestra Studio. Bring in a 3D model view, a sketch, a rendering or a flat photo, and the render keeps up at 15+ FPS as you move the camera, change the prompt or switch style.

If you've used Nano Banana 2, it's the same kind of editing, but much faster.

It starts from your geometry rather than a text box, so the output stays recognisably your building. Changing "timber" to "dark timber" updates the render as you finish typing.

Side by side mode

Your input sits on the left and the output on the right. Pan and zoom around the input freely. The 3D controls adjust the camera and switch between saved preset views, so you can walk a client through north elevation, courtyard and interior in one sitting without queuing a render for each.

Blend mode

Blend overlays the input and output with a slider between them. Pull toward the input to check the geometry you started from, toward the output to see the render, or hold it in the middle to see how far the model has moved from the drawing.

That middle position is the useful one in a review. It answers "is this still my building?" without leaving the canvas.

Realtime AI styles in one click

Style chips sit in the prompt bar: Photorealistic, Sketch, Clay, Watercolor, Vector and more. Pick one and the output changes straight away, no extra prompting.

Architects can show a concept as a sketch early and photoreal later from the same model, without rebuilding anything. Interior designers get Clay, which strips colour back to form when a client keeps reacting to the cushions instead of the layout.

Materials, lighting, environments and weather all work the same way. Prompts stay simple because you're adjusting a scene, not describing one from scratch.

Turbo, Balanced and Hi Def quality settings

Three modes, chosen per session:

• Turbo for fast exploration when you're still deciding.
• Balanced for most work, and the one to leave it on.
• Hi Def for the frame you're actually keeping.

How to start a realtime session

Click Connect to start a session. The first connection takes 10 to 20 seconds while compute spins up, then it stays live until you go idle. Fenestra disconnects you automatically to protect your credits, and Connect picks up where you left off.

Realtime doesn't save images automatically, so save the ones worth keeping before you disconnect.

Where realtime fits in your workflow

Set up your model and saved camera views in Edit — Working with 3D Models first, and the session starts with every view already framed. Saved Realtime images can be animated afterwards with Video.

Full setup steps are in the Realtime documentation.
