DynamicEnvironmentMapManager
Generates an environment map at the given position based on scene's current lighting conditions. From this, it produces multiple levels of specular maps and spherical harmonic coefficients than can be used with ImageBasedLighting for models or tilesets.
// Enable time-of-day environment mapping in a scene
scene.atmosphere.dynamicLighting = DynamicAtmosphereLightingType.SUNLIGHT;
// Decrease the directional lighting contribution
scene.light.intensity = 0.5
// Increase the intensity of of the environment map lighting contribution
const environmentMapManager = tileset.environmentMapManager;
environmentMapManager.atmosphereScatteringIntensity = 3.0;// Change the ground color used for a model's environment map to a forest green
const environmentMapManager = model.environmentMapManager;
environmentMapManager.groundColor = Color.fromCssColorString("#203b34");Parameters
An object describing initialization options.

Properties
The intensity of the scattered light emitted from the atmosphere. This should be adjusted relative to the value of Scene.light intensity.
The brightness of light emitted from the environment. 1.0 uses the unmodified emitted environment color. Less than 1.0 makes the light darker while greater than 1.0 makes it brighter.
The percentage of light reflected from the ground. The average earth albedo is 0.31.
Solid color used to represent the ground.
The maximum difference in position before a new environment map is created, in meters. Small differences in position will not visibly affect results.
The maximum amount of elapsed seconds before a new environment map is created.
The position around which the environment map is generated.
The saturation of the light emitted from the environment. 1.0 uses the unmodified emitted environment color. Less than 1.0 reduces the saturation while greater than 1.0 increases it.
