intensityExponent

TypeScript

get intensityExponent(): Promise<number>

Swift declaration

var intensityExponent: Float

The intensity value of the light, defined on a logarithmic scale. An intensity factor is computed as `2^intensityExponent`. The computed value modulates the native value specified in the diffuse and specular textures. Set the intensity to `0` to result in a scale factor of `1`. This uses the unmodified texture's diffuse and specular intensities.
