The Standard Workflow Process of an Exterior 3D Rendering Project at ATRIUM

Every year, more architects, real estate developers, and agents are embracing the power of 3D rendering. At ATRIUM, we’re proud to support these professionals by delivering high-quality exterior renderings that help bring their visions to life. To make each project seamless, we’ve developed an easy-to-follow workflow that we use for every exterior 3D rendering project.

Let’s walk through the key steps that make up our process, so you know exactly what to expect from start to finish.


1. Submitting Your Project Brief

It all begins when we receive your project brief. This is the foundation of a successful 3D rendering project. What should the brief include? Here’s what we recommend:


  • Architectural drawings (plans, sections, elevations)

  • Lighting and mood references

  • Details about the surroundings


Optional but helpful items include sketches, Revit 3D models, and texture samples. The clearer your brief, the smoother the entire process will be.

2. Approving Grayscale Renders

Once we have your brief, our team gets to work creating grayscale, or “clay,” renders. Think of these as the skeleton of your project—they show the core structure and surrounding elements but don’t yet have colors or textures.


At this stage, you’ll review the overall geometry and camera angles. This is your chance to confirm that everything matches your vision or request changes if needed. We typically offer 1-2 rounds of revisions to fine-tune these grayscale drafts before moving on.

3. Approving Color Proof 1 — Adding Materials and Textures

Now, the fun part begins! We add colors, textures, and environmental details to bring your design to life. You’ll see your project in vibrant 2K quality, complete with realistic elements like materials, lighting, greenery, and even people if desired.


During this phase, we encourage your feedback on how the materials and surroundings look. Up to three rounds of minor adjustments can be made to ensure your project feels just right.



4. Receiving Your Final 3d Rendering

Finally, your project reaches the finish line. We fine-tune the render with post-production techniques using Photoshop to adjust lighting, contrast, and color balance. This final touch ensures your images look polished and hyper-realistic. Typically, our renders are delivered in 4K resolution, perfect for print sizes up to A1. Need a different resolution? Just let us know!


At this stage, we’re always excited to hear your thoughts. Your feedback helps us refine our process and deliver even better results for future projects.
