Answer

Short answer:

Rendair AI acts as an accelerator that sits between your raw 3D model and the final image, replacing the time-consuming texturing, lighting, and rendering setup. It allows you to move directly from a basic massing or screenshot to a photorealistic result in seconds, rather than hours.

Overview

In a traditional architectural visualization pipeline, the workflow typically follows a linear path: Modeling → Texturing → Lighting → Rendering → Post-production. The middle stages, texturing and lighting, often represent the biggest bottleneck. They require complex render engines (like V-Ray or Corona), high-end hardware, and significant setup time just to produce a test image.

Rendair AI compresses these middle stages. Instead of assigning materials and setting up sun systems in your 3D software, you simply take a screenshot of your viewport. Rendair uses that visual data combined with a text prompt to generate the final look. This shifts the workflow from "setup and wait" to "prompt and iterate," allowing you to visualize ideas immediately without leaving your design phase.

How it works

Integrating Rendair into your pipeline does not require changing your modeling software. It functions as a bridge between your draft geometry and your final presentation.

1. Create your base: Build your massing or detailed model in your preferred software (SketchUp, Revit, Rhino, etc.).

2. Capture the view: Take a standard screenshot or export a JPG of your viewport. You do not need to apply textures or lights.

3. Upload to Rendair: Use the 3D Base to Render tool. Upload your screenshot and describe the desired atmosphere, materials, and lighting in a text prompt.

4. Iterate instantly: The AI generates a rendered image based on your geometry. If the mood is wrong, you change the prompt, not the model settings.

5. Refine and finalize: Use In-painting to swap out specific details (like changing a chair or adding a tree) and Upscale to export high-resolution images for print or presentation.

Capabilities

Rendair supports specific tasks across different stages of the design process:

• Rapid Concept Visualization: Turn loose hand sketches or "napkin drawings" into realistic concept images to test viability before modeling begins.

• Material Studies: Upload a single untextured 3D view and generate four different material options (e.g., brick vs. timber) in under a minute for client comparison.

• Contextual Editing: Use the Edit tools to remove unwanted site elements (like cars or dumpsters) from site photos or add entourage to a render without re-rendering the whole scene.

• High-Resolution Delivery: Take low-resolution drafts or older renders and use Upscaling to bring them to 4K or 8K quality for final boards.

• Animation: Convert static approved renders into short video clips to show lighting movement or atmosphere without setting up a camera path in 3D software.

Inputs and outputs

Inputs

• Images: JPG, PNG, WEBP, TIFF, HEIC, AVIF.

• 3D Files: Screenshots are preferred for speed, but specific tools support OBJ, FBX, STL, and IFC for object insertion.

• sketches: Hand drawings, iPad sketches, or whiteboards.

Outputs

• Images: Standard downloads are approx. 1MP; Upscale tools deliver 2K, 4K, 6K, or 8K resolution.

• Video: MP4 files for motion generation.

When to use this

• Client meetings: When you need to show three different facade options but only have time to model one geometry.

• Deadlines: When a rendering is required in an hour and there is no time to set up a full render engine environment.

• Early design phases: When you want to validate a massing strategy with realistic lighting before committing to detailed BIM work.

• Social media: When you need to turn a static portfolio image into a video to increase engagement.

Limitations or notes

• Precision vs. Atmosphere: AI is generative. It excels at atmosphere, lighting, and texture but may hallucinate small details or misinterpret complex structural connections. It is best for visualization, not construction documentation.

• Complex Geometry: If your design relies on specific, non-standard furniture that must be exact (e.g., a specific manufacturer's chair), AI might approximate it. For 100% geometric accuracy, Rendair offers a traditional human-made 3D rendering service as a fallback.

• Hardware Independence: Because the rendering happens in the cloud, you do not need a powerful GPU on your local machine to get high-quality results.
