The Sky light library lets you add realistic atmospheric lighting to your scene.
1. Deselect your objects so the panels on the right hand side are in viewport mode.
2. Select the Sky light tab to access all tools for editing the environment.
3. Add a Brio Studio HDR if you want to simulate studio lighting (A). These contain a more dramatic range of light.
You also have the option to add one of the other sky lights (B). These simulate a real environment by reflecting light, colour, and imagery from a photograph onto your scene.
Use the options menu next to the thumbnail to remove a sky light. You can also use the UPLOAD button if you want to add your own HDR image.
The intensity of the reflection will depend on the materials in your scene and pixel brightness in your HDRI image.
