Lock a base image
Render the scene once and agree on it. Every variation then starts from the same image.

GPT Image 2 Material Variation Render
Test material and color options on one render with GPT Image 2 in RenderChat. Upload your render or model view, describe what you want, and refine the render in chat.

Drag to compare the render or model view with the GPT Image 2 render. Input is an AI-generated example.
Before you start
Prepare your render or model view
Material decisions are easier when options sit side by side in the same image. Start from a render or model view, then ask RenderChat for one change at a time — cabinet color, worktop stone, facade cladding — while the rest of the scene stays put.
Change one thing per message
One material per request makes it clear what changed and keeps the rest stable.
Use real samples
Attach a photo of the actual material sample when color accuracy matters.

Prepare your render or model view
Lock a base image, change one thing per message and use real samples. The checklist above has the details.
Open RenderChat with GPT Image 2
The start button on this page opens a new chat with GPT Image 2 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 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
Material variations briefs to start from
Copy a brief, paste it into RenderChat with your render or model view, and change the materials and mood to match your project.
Keep everything in this kitchen render exactly the same and change only the cabinet fronts to dark green lacquer.
Keep everything the same and change only the worktop and splashback to terrazzo with small white and ochre chips.
GPT Image 2 in RenderChat
Working with GPT Image 2
OpenAI's GPT Image 2, run in RenderChat as a native conversation through OpenAI's Responses API, so follow-ups continue the same image thread.
- Useful as a comparison point against GPT Image 2.5 on the same model view.
- Keep one design change per message so you can tell which instruction moved the image.
Quality check
What to check before you share it
- Areas that changed but should not have — compare with the base image.
- Color accuracy against the physical sample under similar light.
- Reflections and shadows updating with the new material.

FAQ
GPT Image 2 Material variations questions
Is GPT Image 2 available on the free plan?
GPT Image 2 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 GPT Image 2 render at?
GPT Image 2 renders at 1K in RenderChat, with auto + 10 fixed ratios.
Can I keep refining a GPT Image 2 result in chat?
Yes. GPT Image 2 runs as a native conversation in RenderChat, so each follow-up continues from the previous turn. Short edit instructions work well.
How do I select GPT Image 2 in RenderChat?
Use the start button on this page — it opens a new chat with GPT Image 2 selected — or choose it from the model menu in the chat composer.
How do I stop the rest of the image from changing?
Ask for a single change and say everything else stays. Check the result against the base image and correct anything that moved.
Can I match a specific product?
Attach a photo of the product or sample. The render is an approximation, so confirm the final color with the physical sample.
