Before you start
Prepare your Archicad 3D view
Archicad's 3D window already holds your design. Save the perspective you want, describe the finishes and setting, and use RenderChat to explore how the building could look before you set up a full rendering pass.
Choose a 3D style
Use a shaded 3D style with contours on and sun shadows enabled. Hide markers, grids and section planes.
Save the 3D window
With the 3D window active, use File ▸ Save As and choose PNG at 2000 px or wider. A full-screen screenshot also works.

Prepare your Archicad 3D view
Set the perspective, choose a 3D style and save the 3D window. The checklist above has the details.
Open RenderChat with GPT Image 2.5
The start button on this page opens a new chat with GPT Image 2.5 Sunburst selected. You can also pick it from the model menu in the composer.
Upload and write the brief
Attach the image and say what must stay, then the materials, light, setting and people. Start from an example brief below.
Refine in chat
Ask for changes in follow-up messages. GPT Image 2.5 continues the same conversation, so a short instruction such as "warmer light, keep everything else" is enough.
Download the render
Download the image at the resolution you chose (1K).
Example briefs
Archicad briefs to start from
Copy a brief, paste it into RenderChat with your Archicad 3D view, and change the materials and mood to match your project.
Photoreal render of this Archicad model. Keep the massing, balconies and window rhythm. Light brick, white render on the top floor, timber balcony soffits, planted courtyard, spring morning light.
Street-level photoreal render from this Archicad view. Keep the building and camera. Wet pavement after rain, warm lights in the windows, cyclists and pedestrians, soft overcast light.
GPT Image 2.5 in RenderChat
Working with GPT Image 2.5
OpenAI's GPT Image 2.5, offered in RenderChat as two variants, Sunburst and Flare. Both run as native conversations, so every follow-up message keeps working on the same image thread. Sunburst is RenderChat's default model.
- Start with Sunburst. Switch to Flare in the model menu when you want a second read of the same brief.
- Write follow-ups as edits ("keep everything, warm the light") rather than restating the whole brief.
Quality check
What to check before you share it
- Balcony and window counts across the facade.
- Ground-floor entrances and how the building meets the ground.
- Material boundaries on the facade against your design.
