Inputs

Use all Lights

If this option is enabled, all light sources in the scene will be evaluated and their collective effect on the material will be ascertained. If this option is disabled, a separate assignment field will be displayed for the light source whose effect you want to ascertain.

Light

Assignment field or input for linking to a light source.

Specular Exponent [0..99999999]

This exponent flows into the calculation of the specular highlight in connection with the shaded surfaces’ Phong Normals. Smaller values simulate soft, intense specular highlights and larger values sharpen the specular highlights.

Compute Falloff

Inputs the light source’s individual Falloff settings into the calculation. Without this option, all light sources will be calculated with constant intensity.

Compute Shadows

The light sources‘ shadows will also be evaluated in order to calculate the brightness on the surface correctly. If this option is disabled, the light sources will be calculated by the Node as if no shadows were present.
