Environment lights

You can use environment lights to illuminate a scene. Environments are distant spherical lights.

Environment lights can use textures (either cross, mirror ball or latitude/longitude, high dynamic range or not), shaders, or both (in which case the final result is the multiplication of both.)

A blue Library/Lights/EnvLight, an Library/Lights/EnvLight with a HDR texture, a Library/Lights/SkyLight, a Library/Lights/BoxEnv and a Library/Lights/GradientLight.

Create an environment light

1. Add a Lights/EnvLight node.

Setup an environment texture

1. In the EnvLight properties, drag'n drop an environment map or browse the file using Environment Map > EnvMap.
2. Choose the correct settings for the Map Mode, and the Gamma.

If your environment map is an HDR image, it is probably in a linear color space, in that case, choose a Gamma of 1. Setup an environment shader

1. Open the EnvLight in the Node List, drag'n drop the EnvironmentMap node in a view. This will create an environment shader.
2. Create a shader by connecting nodes to the Environment output.

Setup a physical sky

1. Import the Lights/SkyLight from the library. This setup is composed of a physical sky environment and a distant light for the sun direct lighting.
2. Tweak the physical parameters located in the SkyLight root node.
