Answer
Short answer:
You can generate realistic interiors by uploading a photo of an empty room or a screenshot of a 3D model as your base input. By providing a text prompt that describes the desired furniture, lighting, and style, Rendair AI populates the space while respecting the original perspective and structural boundaries.
Overview
Visualizing the potential of an empty space is a common challenge in real estate and interior design. Clients often struggle to understand scale or layout when looking at a vacant room or a "white box" 3D model.
Rendair AI solves this through a process often called virtual staging. Instead of manually modeling every piece of furniture, the platform uses your empty image as a geometric guide. It then interprets your prompt to fill that geometry with realistic textures, furniture, and decor. This allows you to show a fully lived-in space in minutes rather than hours.
How it works
The process relies on guiding the AI with both visual input and text instructions.
Upload your base: Start by uploading a photo of the existing empty room or a screenshot of your 3D model to either Chat or Virtual Staging tool. Supported formats include JPG, PNG, HEIC, and WebP.
Describe the interior: In the prompt area, describe the style and function of the room. For example: "Modern living room with a beige linen sofa, oak coffee table, sunlight coming from the window, 4k realistic."
Adjust influence: If you are using a 3D model screenshot, you can choose between maintaining strict structural accuracy or allowing the AI more creative freedom to add realistic details like curtains, rugs, and lighting fixtures.
Generate and refine: The system generates options based on your prompt. If the furniture placement is not quite right, you can use the editing tools to remove specific objects or re-generate with a modified prompt.
Inputs and outputs
Inputs
Base Images: Photos, 3D screenshots, or sketches.
File Formats: JPG, JPEG, PNG, WEBP, TIFF, HEIC, AVIF, and single-page PDF (converted to JPG is recommended).
Max Upload Size: 10MB.
Outputs
Resolution: Default generations are approximately 1MP (or 2K for specific models).
Upscaling: You can upscale selected results to 2K, 4K, 6K, or 8K for final presentations.
Aspect Ratio: The output inherits the aspect ratio of your uploaded base image.
When to use this
Real Estate Marketing: When you need to list a property that is currently vacant or under construction.
Early Design Phases: When you have a massing model and need to quickly communicate the "vibe" of the interior without detailing the 3D assets.
Client Meetings: When a client asks, "What would this look like with different furniture?" and you need a visual answer immediately.
Limitations or notes
Structural Accuracy: While the AI respects the general perspective, it may occasionally misinterpret complex geometry. For 100% architectural precision, traditional rendering or the Rendair human-made 3D service is recommended.
Detail Consistency: At standard resolution, small details might appear soft. Always use the Upscale tool before using the image for professional presentations.
Creative Freedom: If your base image is very low detail (like a wireframe), the AI will take more liberties to fill in the gaps. If your base image is a high-res photo, the AI will adhere more strictly to the existing lighting and structure.
