3D Interior Design and Rendering Tips Companies and Firms use for Bedrooms

3d interior design & rendering firms

Every bedroom rendering in 3D interior design requires a different approach because what works for one area doesn’t apply to another. In architectural rendering, camera angle, composition, and field of view can affect how people perceive objects and capture the mood in the frame. Although the 3D models play a crucial role in the render’s aesthetic aspect, they are not the only determining factors. The visual style and mood, both of which are products of lighting setup, help create the three-dimensional space from a two-dimensional image.

A professional 3D interior rendering design artist most likely has an arsenal of software tools. More importantly, each has a signature touch/style to differentiate the image from competitors. No one-size-fits-all rule is used to create bedroom renderings, but the following tips will make the image work best for interior design rendering.

Lifestyle objects 

A sterile space might showcase technical proficiency and demonstrate a clinical, almost lifeless approach to 3D interior design and rendering. When it comes to bedroom renderings, one of the most important things is to let viewers imagine themselves occupying the space, using every available inch as a personal retreat in comfort and privacy. An apparent lack of human touch can turn the room into a bland chamber devoid of emotion. Decorations and small details make a huge difference in how the space feels.

Utilizing lifestyle objects like potted plants, light-reading books with tasty covers, or a pencil and a notepad on the nightstand are effective 3D architectural rendering techniques used by a 3D architectural visualization company. All those small items gave an instant personality to the design. However, be mindful of the clutter. While decorative objects liven up the render, going overboard with small objects can ruin the composition and distract viewers from the bigger picture.

Lighting matters

Photorealistic lighting is often regarded as the most significant accomplishment 3D interior design render artists can achieve. The only problem is that photorealism can appear dull. A good bedroom rendering should lead the viewer to the focal point or the design highlights. Professional 3d interior design software offers a myriad of tools to optimize the lighting setup. Among the most heavily utilized features is the “three-point” lighting configuration. It is one of many techniques available, but it works great for bedroom renders. As the name suggests, the design benefits from three different lights:

  • Key light: this is the brightest source of light in the frame. The ideal position is a 45-degree angle (right or left) from the camera.
  • Fill light: it has lower brightness and is positioned 90 degrees relative to the key light.
  • Backlighting: the dimmest light source of the three and is meant to help separate the foreground objects from everything behind them. The best backlight position is around a 180-degree angle opposite the fill light.

Three-point lighting setup is especially effective in leading viewers to a specific 3D architectural rendering focal point. If the bedroom is large enough that highlighting a single object seems unlikely, the same setup can still work if you don’t use spotlights (directed rays). Consider using these light sources instead:

  • Area lights: when emitted from a wide area (but not directly to the scene), they work best to represent fluorescent bulbs. You can make the light appears as if it is coming through a window or sheer curtain.
  • Omni lights: a source of light that casts brightness to all directions, commonly used as fill lighting.
  • Line lights: the brightness is spread evenly across the room with linear light.
  • Sun: non-directional soft light of which the brightness is distributed evenly throughout the scene.

Natural lighting is ideal in most rendering scenarios, including interior design rendering. “Natural” means the lighting is not overly bright and casts hard shadows from every object, and the illumination should allow viewers to see objects without squinting their eyes. An obvious scene selection for the bedroom interior design render is a sunny day with heavy clouds. The sun is the key light source, but the clouds are a natural filter to soften the brightness.

The 3D interior design rendering artist uses warm lighting to make the room feel more comfortable and welcoming. Cold lights can be harsh on the eyes, creating an active and energetic mood. Either option is used for interior design bedroom renderings, depending on the atmosphere you want to convey. Whether you use a natural or artificial light source for interior design rendering does not matter. Remember that bedroom often implies a soothing (sometimes romantic) environment, so viewers usually prefer warm to cold tones.

Shadows are integral parts of photorealistic rendering services and interior design rendering that you cannot have without lighting. It is impossible to create the right ambiance using a single light source. Since the interaction between light sources can be predictable, consider isolating each source to see how it contributes to the brightness level and shadows.

Window views

A decisive advantage of 3D interior design rendering is that the window views work to your benefit. CGI allows you to project scenery of any sort to complement the 3D interior design and bedroom render. More than just a complementary element, the outside view adds to the visual effect. Depending on the scenery, the view enhances spaciousness, privacy, or luxury.

The window views can be from a photograph superimposed on the scene, or the photorealistic rendering artist may create every object from 3D assets. It’s possible to use a combination of the two. Much like the lighting setup in the design itself, the scene can always look perfect in a render. The limit is the interior design rendering artists’ skills. You get to choose the weather, from bright summer days or snowy winter.

Photorealism concerns the lighting as much as it does the 3D objects when used for architectural rendering. Quality 3D interior design rendering requires quality 3D assets, too. Making a digital object appear identical to its physical counterpart is only possible with realistic textures and colors. The surface material and color will also affect the behavior of light hitting the object; a material may reflect, deflect or refract the light. The intensity of its shadows changes accordingly. It is essential to make the rendering of an object look the same and share the same properties as the physical item it represents. 

Things to consider when applying a texture to an object in a 3D interior design bedroom render:

  • Roughness: the degree of roughness can be entirely different in two closely positioned objects. For example, a scene depicting a glass of beer on a wooden table encompasses various textures. The glass is transparent, but the beer might be translucent if it is cloudy enough. On the other hand, the table can be reflective only when the finish is shiny. Each can be given a specific degree of roughness to ensure light behaves differently when it hits objects.
  • Bump: while flat surfaces look tidy, bumpy surfaces give depth for a 3D effect. Flexible objects (and materials) like carpets or blankets should come with bumps in certain spots to appear realistic.
  • Reflections: reflective mirrors should show adjacent objects as reflections.

For 3D interior rendering purposes, many textures are free from online sources, such as 3DXO, CC0 Textures, and 3D Textures.

Camera settings

It is only appropriate that every 3D interior design render artist wants their images to look like professional photographs. The phrase “render like a photographer” is a common expression in CGI. Like a photographer, a 3D architectural rendering artist adjusts the camera and lighting to get the perfect 3D architectural renderings. 

Elevation and Pitch

In photography, a tripod isn’t only for ensuring the camera is steady. A tripod helps the photographer capture the object from an optimal height. 3d interior design bedroom rendering is no different in this case. An excellent interior render should show the floor and ceiling, albeit not the entire length and width. If the camera sits too low, the image will include too much ceiling; if it is too high, the floor is the dominant feature. As a rule of thumb, a balanced 3D rendering requires the camera to sit at half the room’s height. The camera must be set at five feet if the ceiling is ten feet high.

Once the camera height is set for the 3D interior design, the viewing angle comes next. Use pitch adjustment to include a little more detail of the ceiling or floor. A slight downward pitch looks natural because it replicates how a person looks at a bedroom in real life. Consider where the tripod might be positioned when taking the picture. Most photographers will take their shots at an angle at the entry point of the room simply because it works best to cover a large area of the space. Another popular architectural rendering position is the corner, but you should avoid aiming the camera at the opposite corner as it might appear unnatural. Rotate the camera to a light degree, so the corner is off to one side. Such a viewing angle gives the audience a feeling of movement and spaciousness. 

Focal Points

3D bedroom rendering doesn’t differ much from other 3D interior visualization services; the frame needs a focal point. You can create a single or several focal points in a triangular pattern, leading viewers to the most critical objects in the room. The focal points can be lighting fixtures, beds, ornaments, or accessories. The purpose is to help viewers focus on a specific spot at a time instead of the whole image.

Before 3D architectural modeling services render the 3D interior design models, take your time to step back and look at the image for one final scrutiny. It is easier said than done, especially after spending many hours working on small details. Ensure the eye level is correct and the overlapping objects do not create confusion. You want the image to tell a coherent story, not a clutter of objects thrown into the frame together. 3D rendering services for 3D interior design are available to help companies create vivid 3D interior design renderings (i.e., 3D bedroom renderings).
