Product Review: Twinmotion 2020

Architosh reviews Epic’s Twinmotion 2020, a leading real-time interactive photorealistic rendering application for AEC and design markets.

Lighting Improvements

While we have already mentioned the visual benefits of a physically-based sun and sky model, Twinmotion 2020 has additional lighting feature improvements. One small but important one is the automatic exposure adjustments to areas of shade and intense brightness.

Automatic exposure functions in Twinmotion 2020 prevent dark shadows from being too dark.

Shady areas now have more light enabling greater visual detail from both ground and vegetation in these darker areas in a scene. Meanwhile, over-exposure of sun-drenched lighter areas of the scene is also implemented. Both contribute to more realistic higher-quality renders.

You can also manually adjust exposure and white-balance levels in the Camera tool settings. Another lighting feature is the new volumetric lighting effects, visible with smog settings and specific light types.

Smog in Twinmotion 2020 set at a low level, with physical sunlight penetrating the sunlight volume.

The smog is increased to 100 percent and light penetrates less through that volume.

There are also lens flares when combined with the depth of field (DoF) improvements, provide cinematic qualities found in much more expensive and more difficult to learn rendering programs.

Lens flares provide stunning cinematic visual qualities, particularly when combined with DoF effects.

Area lights are another new feature in Twinmotion 2020. Another type of light “type” you can provide even light to a specific dimensional area and provide the length and width dimensions along with other settings like attenuation, shadows, et cetera.

Another lighting feature is a light-emitting glow material that you can apply to an object. This instantly turns that into a light source but it only works when the object is in the camera’s view. You can’t use it off-scene and expect its light to come pouring into the visual scene.
