It takes a balance of light and material, perspective and composition to create an authentic interior. As an architect or interior designer, rendering beautiful 3D interiors may be your favorite part. Or, it may be fraught with virtually endless nitpicking and irritation.

The smallest changes in lighting and shadow can make a big difference in smaller spaces.

Tips For Lighting Your 3D Render

Many architects and designers consider photorealistic lighting to be the ultimate goal. Photorealism can sometimes be boring. Good 3D interior rendering should depict a place that the viewer would like to visit.

The three-point lighting system is a popular technique that you can use today.

The key light, which is the brightest source of light, should be placed at a 45-degree angle to the camera. The fill light, which has a lower brightness, can be placed 90° opposite to the key light.

The backlight is the lowest setting and casts a soft, fine light that separates the object from its background.

When you are focusing on an object, three-point lighting can be especially useful. This technique can be used in 3D interior settings even if there isn't a specific object. Instead of using spotlights to produce a beam of directed light, you can use the following light sources.

The sun: a soft, non-directional light that diffuses evenly across the scene.

Line lights: a linear light with an even profile.

Finally, by using ambient lighting and mood, you can create a feeling for your audience.
