intensityExponent

The intensity value of the light, defined on a logarithmic scale.

Declaration

var intensityExponent: Float

Discussion

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.
