Environment settings

This section of the Display Settings controls the lighting in the viewport.

Environment

Setting	Description
Environment Map	Environment map texture to be used to light the scene. Can be found in the Assets window by using the "Environment" preset. Click on the button to open a mini-shelf and choose a different environment map.
Override environment map color space	If the current project use Color management, this setting can be enabled to override the color space of the environment map.
Environment Opacity	Controls the visibility/opacity of the environment textures in the background of the viewport. This settings has no impact on the lighting of the scene.
Environment Exposure	The exposure value (EV) is a number that represents a fixed scene luminance. This setting allows to offset the default luminance value.This setting should stay on 0 when working with the environment maps provided with the application. Texturing an asset with an incorrect exposure value could lead to color calibration issues in other applications.
Environment Rotation	Controls the horizontal rotation of the environment texture. Useful for rotating the lighting in the scene and change how the object react. Can be controlled with a shortcut.
Environment Blur	Controls how sharp or blurry the environment texture will appear in the background of the viewport. This settings has no impact on the lighting.
Environment Alignment	Controls how the environment texture rotate around the 3D mode inside the viewport. This setting can be used to light up areas under the 3D model when set to local. Possible values: World (default): the environment is aligned with the scene and rotate around the up axis of the 3D model. Local: the environment is aligned to the camera and rotate around the up axis of the camera.

Shadows

Setting	Description
Shadows	Enable / Disable rendering of shadows in the viewport.
Computation mode	Controls how quickly the shadows are computed. Intensive : Compute fast but can froze the rendering of the viewport. Average : Average of the Intensive and Lightweight mode. Lightweight : (default) Compute slowy the shadows over a few seconds but doesn't slow down viewport performances.
Shadows opacity	Controls how much Shadows will be visible in the scene.
