Creating a truly photorealistic 3D rendering takes incredible skill, time, and industry experience. However, even the most professional 3D rendering artist’s work may lack that finishing touch that keeps the image from being believable. Often times, the viewer can’t pinpoint exactly what it is that’s holding the rendering back, and the artist themselves may never find the answer.
When this happens, it’s often in the details. So today, we’re sharing four of BluEnt’s tips for photorealistic rendering that will change how you see architectural visualization.
Tip #1: Never use colours that are 100% black or 100% white.
This tip is by far the easiest, and you’ll notice results as soon as you implement it. To achieve photorealistic architectural renderings, you need to have a balance of highlighted areas, shaded areas and mid tones. These bring out the dimension and volume of the objects in the rendering. Materials that are 100% black or 100% white make it impossible to differentiate between the mid tones and shadows or highlights respectively, which results in flat-looking objects that no one will believe.

To avoid washing out light areas, cap colours and textures at a brightness value of 80%. Even for perfectly white items like a blank piece of paper, a higher diffuse white value won’t look real. As for dark areas, don’t let their brightness values fall below 10%. Staying within this range will keep the image from looking overexposed or underexposed effortlessly.
Not only does this give the rendering a natural sense of balance, it also improves render times by keeping your values in check.
Tip #2: Strive for (im)perfect texture.
When it comes to texturing, you could master the perfect texture tiling, scaling and positioning techniques and still not produce the photorealistic rendering solidworks results you’re looking for.
Many architects are not the first to ask for dirt and imperfection in the final rendering, but trust us – nothing makes a project more authentic. It’s helpful to think about how your model would react to natural weathering and exposure to the elements, and recreate hints of these effects in the rendering.
Adding different types of variation to repeating textures and slight bumps and scratches on smooth surfaces go a long way in creating overall realism to the image. Similarly, try veering away from the default symmetrical lines and shapes provided by CAD software and incorporate some asymmetric variance to textural details. This will make the rendering more dynamic and true to life than the infinite identical textures associated with CGI.
BluEnt’s team of skilled professionals have worked on a wide variety of different projects for real estate developers, interior designers, architectural, and marketing firms over years of industry experience. As a result, we have perfected the art of creating convincing textures regardless of the objects and settings of the architectural rendering requested. We stand by our commitment to high-end photorealistic results with quick turnaround time and affordable cost that never sacrifice quality.
Tip #3: Always use area shadows and reflections.
Area shadows are a lifesaver for capturing that perfect diffused light in a photorealistic 3D rendering. Take different times of day, for example. Morning light creates very soft shadows that get progressively sharper until mid day, after which point it begins to soften again until the daylight disappears. Keep in mind that even at high noon, shadows are not 100% sharp; you still need to use area shadows to add a touch of softness to the edges.
This applies to artificial as well as natural lighting. Different fixtures cast shadows of varying subtlety and sharpness depending on the context. Area shadows are perfect for achieving these different levels of diffusion with different parameters.
Furthermore, a common mistake in 3D models is to omit surface reflections. In the real world, reflections are everywhere and almost no area is lit with pure diffuse. To add to the foundation you create with area shadows, take into account the surface glossiness of your objects and increase reflection intensity accordingly.
Tip #4: Use depth of field to your advantage.
Depth of field effects are an interesting way of creating photorealism in 3D animation because it plays off the technique’s association with the art of photography. It tricks the viewer into believing that they are seeing an impermanent captured moment of a dynamic setting as opposed to a static computer generated model.
The effect is naturally more obvious in close-up shots where the elements in the foreground are at noticeable distance from the elements in the background, but it can also be applied strategically on large scale scenes. A shallow depth of field is a subtle way of isolating the focal point of the rendering while blurring elements in the image that are of lesser priority, allowing you to concentrate on achieving photorealistic details where they will count the most.
Depth of field can also improve the overall composition of the image when used correctly. It not only frames objects in an advantageous way, but also forces you to pay attention to how you layer the rendering. Actively choosing what objects to place in the foreground, middle ground and background helps you fully profit from the human eye’s depth perception, again recreating the experience of seeing a real life photograph.
BluEnt works with the latest hardware and software including 3D Studio Max and Revit for all 3D rendering and animation purposes to ensure that we deliver the most sophisticated results when it comes to highly technical techniques such as depth of field. With BluEnt, you have the option of using our CAD studio model or trying our Revit Modeler or 3DS MAX resource for one month. We provide these experienced 3D rendering resources on a flexible basis to determine what methods and tools are the best fit for your needs and budget.
Effective 3D visualization is a combination of technical tricks and a critical eye. Armed with these tips, your photorealistic renderings will be improved by tenfold. If you want to learn more about how we accomplish this with the BluEnt CAD Studio Model, fill out a form today.
