Keep the massing white
Plain white or grey volumes with shadows on. Context buildings in a slightly darker grey help separate them.

FLUX.2 Pro Massing Model to Render
Turn white massing models into context renders with FLUX.2 Pro in RenderChat. Upload your massing model view, describe what you want, and refine the render in chat.

Before you start
Prepare your massing model view
Early massing studies are about volume, height and how a building sits in its context. Export the white model, describe a facade approach and the setting, and test several architectural expressions on the same massing in RenderChat.
Choose the eye
A street-level view tests how the building feels; an elevated view tests how it sits in its block.
Write the facade idea
Describe the facade approach in a sentence: brick with deep reveals, a glass box with fins, timber screens.

Prepare your massing model view
Keep the massing white, choose the eye and write the facade idea. The checklist above has the details.
Open RenderChat with FLUX.2 Pro
The start button on this page opens a new chat with FLUX.2 Pro 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. Each FLUX.2 Pro request is sent fresh from your latest image, so repeat the constraints that matter.
Download the render
Download the image at the resolution you chose (1K).
Example briefs
Massing model briefs to start from
Copy a brief, paste it into RenderChat with your massing model view, and change the materials and mood to match your project.
Turn this massing model into a photoreal street-level render. Keep the volumes and heights exactly. Red-brown brick with deep window reveals, a glazed ground floor with shops, street trees and people, overcast light. Render the grey context buildings as existing city blocks.
Same massing and camera. Facade of floor-to-ceiling glass behind vertical timber fins, planted roof terraces, warm evening light.
FLUX.2 Pro in RenderChat
Working with FLUX.2 Pro
Black Forest Labs' FLUX.2 Pro. RenderChat sends it one complete edit request at a time, built from your source image, references and the instruction agreed in chat.
- Because each request stands alone, restate the important constraints when you ask for a variation.
- Compare it against a conversational model on the same view before committing to a direction.
Quality check
What to check before you share it
- Heights and setbacks — massing is the one thing that must not change.
- The number of floors the AI implies through windows.
- Context buildings staying in the background.

FAQ
FLUX.2 Pro Massing model questions
Is FLUX.2 Pro available on the free plan?
FLUX.2 Pro is available on the Pro plan. On the Free plan you can use GPT Image 2.5 and Nano Banana 2.1.
What resolution does FLUX.2 Pro render at?
FLUX.2 Pro renders at 1K in RenderChat, with auto + 10 fixed ratios.
Can I keep refining a FLUX.2 Pro result in chat?
Yes. Each follow-up is sent to FLUX.2 Pro as a fresh request built from your latest image and instructions, so restate the constraints that matter.
How do I select FLUX.2 Pro in RenderChat?
Use the start button on this page — it opens a new chat with FLUX.2 Pro selected — or choose it from the model menu in the chat composer.
Can I compare several facade options on one massing?
Yes. Keep the same view and send a new facade description each time, or ask for variations in one chat and compare them side by side.
Is the render accurate enough for planning?
Treat it as a design-exploration image. Planning and competition submissions still need verified views from your model.
Try FLUX.2 Pro on your massing model view.
