How detailed should my sketch or image be before uploading?
Your sketch does not need to be detailed. Clear lines, correct proportions and the main elements such as walls, openings and the roof are enough. Rendair adds materials, light and context based on your prompt. A short description of the materials and style helps most, especially for very rough sketches.

Your sketch or image does not need to be detailed. Rendair works from the main shapes and adds materials, light and context from your prompt.
What to include
- Clear lines for walls, openings and the roof.
- Correct proportions, for example the height compared to the width.
- The main elements you want to keep, such as the entrance or a large window.
When to add more detail
Very rough or unclear sketches can lead to surprises. Add a short description of the materials, style and setting in your prompt to guide the result. If something is important, such as the number of floors, mention it.
Tips
- Dark lines on a white background work best.
- Avoid very small, blurry or heavily compressed images.
