Lesson 7: Environment

Set up the world around your objects — lighting, sky, and fog.

Concept: Lighting, skybox

environment "DaytimeForest" {
  skybox: "forest_day.hdr"
  ambientColor: "#b0c4d8"
  ambientIntensity: 0.6
  fog: { color: "#c8d8e8", near: 20, far: 80 }

  sun {
    direction: [0.3, -1, 0.5]
    color: "#fff5e0"
    intensity: 1.2
    castShadow: true
  }
}

Environment properties

Property	Type	Description
skybox	string	HDR panorama path or URL
ambientColor	color	Global fill light color
ambientIntensity	number	Fill light brightness
fog	object	Atmospheric depth cueing

Try it:

environment "Night" {
  skybox: "starry_night.hdr"
  ambientColor: "#0a0a2e"
  ambientIntensity: 0.2

  sun {
    direction: [0, -1, 0]
    color: "#ffffff"
    intensity: 0.1
  }
}

Your turn:

Add a fog block to the Night environment that starts at 10m and fully obscures at 50m.
