Steps
Once connected (see setup above), use the Interior Design tool:
- Provide the room photo and the intended mood or function — entertaining, working, relaxing.
- Run `change_lighting` via interior-design to generate the updated room render.
- Ask ChatGPT to describe the lighting setup shown and write a brief specification for an electrician.
- Request a second lighting scenario for comparison if needed.
Example Prompt
Try this with ChatGPT using the Interior Design tool
Use interior-design with change_lighting to transform this home office from harsh overhead lighting to a warm, layered setup with desk task lighting and ambient wall lights. Return the render and write a brief lighting spec I can hand to an electrician.
Tips
- Include the room's primary function — working, entertaining, sleeping — so the lighting type is appropriate.
- Ask ChatGPT to list fixture types and approximate positions so the spec is actionable, not just descriptive.
- A lighting render plus a written spec gives an electrician everything they need to quote the job.
