GPT Image 2.5 Render Enhancement
Make Enscape, Lumion and V-Ray renders more photoreal with GPT Image 2.5 in RenderChat. Upload your existing render, describe what you want, and refine the render in chat.

Before you start
Prepare your existing render
Real-time engines are fast, but their images can look flat: plastic materials, sharp shadows, repetitive trees. Upload the render from Enscape, Lumion, Twinmotion, D5 or a quick V-Ray pass, and ask RenderChat to push it toward photography while keeping the design and composition.
Say what stays
Geometry, camera and color palette usually stay. Say so explicitly.
Name the weak spots
Point at what looks fake: vegetation, glass reflections, people, sky.

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
Render enhancement briefs to start from
Copy a brief, paste it into RenderChat with your existing render, and change the materials and mood to match your project.
Make this render more photoreal. Keep the composition, geometry and colors. Richer material texture on the timber and concrete, softer shadow transitions, natural-looking vegetation, realistic glass reflections, a more believable sky.
Keep everything the same and replace the people with natural, candid figures in casual clothing, slightly motion-blurred.
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
- Design details the enhancement should not alter: window divisions, signage, furniture.
- Colors drifting from your palette.
- Over-sharpening or an artificial look on faces and foliage.

FAQ
GPT Image 2.5 Render enhancement questions
Is GPT Image 2.5 available on the free plan?
Yes. GPT Image 2.5 is available on the Free plan as well as Pro.
What resolution does GPT Image 2.5 render at?
GPT Image 2.5 renders at 1K in RenderChat, with auto + 10 fixed ratios.
Can I keep refining a GPT Image 2.5 result in chat?
Yes. GPT Image 2.5 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 2.5 in RenderChat?
Use the start button on this page — it opens a new chat with GPT Image 2.5 Sunburst selected — or choose it from the model menu in the chat composer.
Which renderers' output can I enhance?
Any image: Enscape, Lumion, Twinmotion, D5 Render, V-Ray, Corona, Cycles or a screenshot. The enhancement works from the pixels, not the scene file.
Will it upscale my render too?
Choose the output resolution in RenderChat when the model offers more than one. Enhancement and resolution are separate settings.
