Environment Radiance (RealityKit)

Returns an environment’s diffuse and specular radiance value based on real-world environment, and an IBL map that is either a developer-provided map or a default map.

Parameter Types

Parameter descriptions

Base Color

The base display color of the surface. The color under pure white light.

Roughness

The level of roughness of the surface. This value ranges between 0 and 1.0, with 0 representing a perfectly specular surface and 1.0 representing maximum roughness. The default value is 0.

Specular

The level of specular reflections that occur on the surface.

Metallic

The indicator if a surface is metallic or not. Set this value to 1 for metallic surfaces and 0 for nonmetallic surfaces. The default value is 0.0.

Normal

The surface normal vector. The default value is (0,0,0).

Discussion:

The Environment Radiance node has two outputs:

Diffuse Radiance

The diffuse radiance of the surface. Refers to light absorbed by the surface and then re-emitted in all directions.

Specular Radiance

The specular radiance of the surface. Refers to light reflected off of the surface.
