It’s the holiday season. A small seasonal tweak can go a long way in making your visuals feel thoughtful, timely, and memorable for clients.

With a few simple prompts, you can turn existing interior or exterior renders into festive Christmas scenes - no re-modelling, no re-rendering, no back-and-forth. For best results, use Flux 2 Pro or Nano Banana Pro. I personally recommend Flux 2 Pro for anything atmospheric or cinematic.

My go-to setup:

• Model: Flux 2 Pro
• Resolution: 1MP (gives the model more room to breathe)
• Final polish: Clarity Upscaler for crisp detail

The more you test these models, the more you’ll understand where each shines.

Step 1: Start with any image

• A sketch → use Sketch to Render
• An existing render → start directly from that
• A 3D model → set your camera view first

Once you have your base image, you’re ready.

Step 2: Use Conversational Edit

For this walkthrough, we’ll only use Conversational Edit (no reference images). If you do want to influence the style with a specific image, you can use Add Anything to include reference images.

Step 3: Choose a decoration style

Below are three prompt styles you can copy, paste, and tweak depending on the client or project tone.

1. Elegant / Modern Christmas Subtle, premium, client-safe

“Add tasteful Christmas decorations to the image. Subtle tinsel, modern Christmas trees, warm interior lighting, soft festive accents, evening atmosphere, snowy exterior. Keep the space elegant and minimal.”

2. Maximalist / Over-the-Top Christmas Fun, playful, attention-grabbing

“Make the Christmas decoration intentionally overbearing. Inflatable snowmen and Santa, excessive Christmas lights everywhere, bold festive colours, playful decorations covering the house, snowy environment, strong warm glow inside.”

3. Modern & Minimal Christmas Clean, restrained, architectural

“Without changing the contents of the space, add restrained Christmas elements. Simple trees, minimal lighting, subtle festive accents, warm interior glow, evening scene, light snow outside.”
