The information you give AI decides the design it generates. Here are the seven inputs that produce better renders: starting image, materials, light, style, and more.
The best results come from providing seven things: a starting image (a photo of your space or a view of your model), the space and its purpose, specific materials and finishes, the light, a clear style or reference, the camera or view, and any constraints about what to keep.
Give the AI vague input and you get a generic result; give it specific, complete information and you get your design rather than a generic one. The single most valuable input is the starting image, because a photo or model view anchors the render to real proportions instead of leaving the AI to invent them.
Below: the exact information to include, why each piece matters, and a reusable checklist you can run through before every render.
Seven inputs, from most to least foundational.
| Input | What to give | Why it matters |
|---|---|---|
| Starting image | A photo of your space or a model view | Anchors the render to real proportions |
| Space & purpose | The room or building, and how it's used | Sets the right context |
| Materials & finishes | Specific ones ("oak floor, honed marble") | Turns generic into believable |
| Light | Direction and time of day | Makes the scene read realistically |
| Style or reference | A named style, or a reference image | Steers the overall look |
| Camera / view | Angle and lens ("eye-level, wide-angle") | Frames the design well |
| Constraints | What to keep (layout, a fixed element) | Protects what shouldn't change |
Provide these and you've given the AI everything it needs; skip them and it fills the gaps with guesses.
Because it gives the AI real geometry to work from. Text alone asks the AI to imagine a space; a starting image hands it one. When you begin from a photo of your actual room or a view of your model, the proportions, layout, and scale are already true, so the render reflects your real space rather than an invented one.
This is the difference between "a nice modern living room" and "my living room, restyled." For designers and architects, it also means the client sees their actual project. Whatever else you provide, start from an image — it's the input that does the most work.
Specific materials, a clear light direction, and a style reference. After the starting image, three inputs move the needle most.
Run through this before you generate:
If you can tick all seven, your input is complete — and complete input is what produces a design worth presenting.
Better AI design comes from better input. Give the AI a starting image, the space and its purpose, specific materials, a clear light direction, a style or reference, the camera, and any constraints — and it generates your design rather than a generic one. The starting image matters most, because it anchors real proportions; specific materials and light matter next. Run the seven-point checklist before each render, and you'll get results worth showing a client, in about 60 seconds.
What information should I give AI to get a better design render? Seven things: a starting image (a photo of your space or a model view), the space and its purpose, specific materials and finishes, the light direction and time of day, a clear style or reference, the camera angle, and any constraints about what to keep. The starting image matters most; specific materials and light matter next.
Why do my AI designs come out generic? Usually because the input is vague or missing a starting image. "Modern living room" gives the AI little to work with, and text alone leaves it to invent proportions. Add specific materials, a clear light direction, and a style reference, and start from a photo of your space or a model view.
Does giving a reference image help AI generate a better design? Yes. A photo of your actual space anchors the render to real proportions, so the result reflects your room rather than a generic one, and a style reference image guides the overall look. Starting from an image is the single most effective way to improve an AI design result.
