Before you start
A readable base image and, if useful, a material or lighting reference. Your ChatGPT session needs an image generation or editing tool to produce images. The skill supplies instructions, not that tool.

1. Download the skill
Download the ZIP pack below and keep it without extracting it. The standalone SKILL.md file is also available under details, with the exact filename required by the importer.
Download the ZIP pack ↓2. Import the skill into ChatGPT
On the skill import screen, select the downloaded ZIP and complete the import. Then open a conversation and ask ChatGPT to use the “rendu-architectural-fidele” skill. If your interface does not offer skill imports, paste the contents of SKILL.md into the conversation as instructions.
3. Add reference images
Attach the base image to transform. If you add another image, identify its role: materials, lighting or furniture. An aesthetic reference must not replace your project geometry.
4. Describe the permitted changes
Use the request below. Specify the materials and mood. For an edit, start from the last approved image and identify only the area to change.
A request to try
Use the rendu-architectural-fidele skill. Turn this sketch into a photorealistic architectural rendering. Preserve the visible volumes, storey count, openings, roof and framing. Apply only matte white render and neutral natural light. Do not add floors or openings. Flag missing information without inventing geometry. Generate the image using the available tool; if no image tool is available, say so and provide a usable prompt.
5. Check the result
- Compare volumes, openings, roof and perspective with the base image.
- Check that only the requested materials and lighting have changed.
- A generated image does not guarantee metric precision or CAD compliance.
