9 Nano Banana Pro Tips Architects Often Overlook

Turn a Screenshot Into a Professional Render With Google Nano Banana

Google Nano Banana can take a simple screenshot from your 3D model or physical model and turn it into a professional rendering in about 30 seconds. What used to take weeks now takes half a minute.

Step-by-step:

• Add the screenshot of your building by clicking the plus icon, then Upload file. This can be a basic screenshot of your 3D model.
• Paste your prompt and fill it out with any information you would like. The hardest part about writing a good prompt is knowing what you want.
• After you’re done, hold control and press enter.

By using this prompt, you can describe your building any way you like. I added vines, birds in the sky, people, god rays, and a fireplace feature. I told the AI exactly what materials I want the building to have.

You can also add extra architectural elements that you haven’t modeled yet. For example, I added coping on top of the wood tower on the right.

You can do this exact same thing with a physical architectural model. Snap a photo of it with your phone and use the prompt to bring it to life. The more descriptive your prompt is, the better your end result will be.

Sometimes Nano Banana will change the perspective of your original image, even if you tell it not to. Just rerun the prompt until it gets it right. If you don’t like anything in your image, tell it to change it in the prompt. I told Nano Banana to change the time of day to sunset.

Decorate or Redecorate a Room With Google Nano Banana

Do you have a room that’s not your vibe and you want ideas to redecorate or remodel it? Google Nano Banana AI can help with that.

For an empty room:

• Click the plus icon and upload an image of your empty room.
• Paste your prompt and fill out details:
  • Design style: I chose Japi.
  • Room type: I told Nano Banana this is my living room.
  • Color palette: I chose 2025 trending design color palette.
  • Key materials or textures: I stuck with the typical Japandy outline - light colored wood, soft textiles, and ceramic elements.
  • Furniture: List exactly what you want or the AI will place whatever it feels like. For this room I wanted:
    • A couch
    • Coffee table
    • Plants
    • A hanging light fixture
    • A media console with a TV on top
    • A creative rug
• Hold control and press enter.

If the walls look a little bare, tell Nano Banana to add decor on the walls. I asked for Japanese inspired decor on the walls.

For a furnished room you want to reimagine:

• Click new chat.
• Add the image of your decorated room.
• Paste your prompt and specify changes. I wanted to change my coffee table, put a nicer blanket on the couch, add decor on the walls, and add more plants by the windows.
• Hold control and press enter.

If anything is off, just tell Nano Banana what to edit, remove, or add.

Create 3D Models From an Image With Google Nano Banana

3D modeling takes forever, and getting all the curves right can be a massive headache. Now you can generate high fidelity 3D models from an image in seconds. If you have a photograph of your physical model and you want to turn it 3D, this works great too.

• In Nano Banana, add the image of your building and paste your prompt.
• Hold control and press enter.
• Hover over the output image and download it.

Generate the 3D model in Meshy AI

• Open a new browser tab, go to meshy.ai, and sign in.
• Hover over Workspace and choose Image to 3D.
• Under New model you’ll see options like Text to 3D, Image to 3D, Batch images to 3D. If you pay for Meshy AI, you can take multiple screenshots to create a better 3D model. I’m showing it from one image.
• Head to Image to 3D. Click inside the image box to add the image created in Google Nano Banana.
• Make sure Symmetry is on Auto and click Generate.
• On the right side, Meshy AI generates the 3D model.

Texture and download

• Click the image and scrub through it.
• Click Texture at the bottom, then on the left side click Texture again.
• Meshy AI applies texture to your model. After it’s completed, scrub through to make sure it’s what you like.
• If you like it, download it. At the moment, Meshy AI is free to download, although this can change in the future.

Create context buildings from a site screenshot

You can use this same method to create context buildings. If you have a 3D model with no context around it and you want accuracy, go into Google Earth, take a screenshot, then use the same prompt and Meshy AI to create 3D context buildings.

Create + Add Cutout People and Vegetation With Google Nano Banana

A render without people or vegetation is pretty dull and lifeless. Now you can easily create anyone doing anything and add them right into your render.

I’ll show how to create your own cutout people and vegetation.

Cutout people workflow

• Paste your prompt for a person and fill out details. Hold control and press enter.
• Download the result.
• In Photoshop, open the image you created in Google Nano Banana.
• Use the Object Selection tool. Click and drag a box over the figure.
• In the Layers panel, add a new layer and drag it to the bottom.
• Select the layer with the person. Hold control shift and press I to invert the selection, then hit delete. Hold control and press D to deselect.
• You now have a PNG with no background.
• Open your render, drag the PNG in, and adjust the scale.

Add as many people as you want. After you’re done adding all cutout people, hide the bottom layer of the render and save that image out as a PNG.

Integrate cutouts in Nano Banana

• In Google AI Studio Nano Banana, click the plus icon and upload files.
• First add the image of the render, then add the PNG of the people you just created.
• Paste your prompt and hold control and press enter.

Nano Banana does a decent job adding the people and adjusting the lighting, but there are still some hang-ups. If you want adjustments, do it in the prompt bar at the bottom. You can also rerun the prompt to get multiple options to choose from.

Vegetation cutouts

Use the exact same method for vegetation. I grabbed eight plants and uploaded an image of the front of a suburban home. I told Nano Banana to add all these plants into the planting design of the modern suburban home. I asked it to creatively add planting design to the front yard and include all eight plants I uploaded.

Change a Render’s Perspective (POV) With Google Nano Banana

If you created a render and want to nudge the POV or the camera around slightly without editing all your other layers, use Nano Banana.

• Upload the image of your render.
• Choose an appropriate POV prompt and fill it out.
• Hold control and press enter.

Change the Style of Your Image With Google Nano Banana

Styles and trends change constantly. Creating renderings and graphics in a specific style can be difficult and time consuming, but Google Nano Banana can help.

• Upload the image of your render.
• Paste your style prompt and fill it out.
• Hold control and press enter.

Sometimes it’s hard to determine what kind of style you want, so have multiple prompts ready to try. You can transform a single image into many different styles.

Create a Mood Board With Google Nano Banana

Many of us have Pinterest boards or collections of images of buildings, art, or design elements we love. Google Nano Banana can combine these elements into one mood board to help narrow in on the right direction for a project.

Step-by-step:

• Open your reference board and save the images you want in your mood board.
• In Nano Banana, click the plus icon, upload file, and add all the images you saved.
• Paste your mood board prompt, hold control, and press enter.

Generate a Room From a Mood Board With Google Nano Banana

Along the same lines, you can create a new room based on your mood board images.

• Click the plus icon.
• Add all of the images you saved and paste your room-generation prompt.
• Hold control and press enter.

Quickly Add Realistic Entourage to Your Render With Google Nano Banana

I created a base image in MidJourney, then uploaded it into Nano Banana to add people.

• Click the plus icon, upload file, and select the image of your render.
• Paste your prompt to add people. Fill out any details you need.
• Hold control and press enter.

If you still want more people, type a follow-up instruction like add 30 more people to the image, then hold control and press enter.

Final Thoughts

Nano Banana can turn quick screenshots into presentable renders, reimagine rooms, build usable 3D assets from a single image, add cutouts and planting, adjust camera POV, restyle graphics, assemble mood boards, generate new rooms from references, and populate scenes with entourage. The key is clear prompts, specific details, and a willingness to iterate. When something looks off, tell it exactly what to change or rerun the prompt until the result fits your vision.
