Spectrum (Material global keyword)

Description

Restricts light interaction to those lights with a matching spectrum. Without a matching spectrum, no illumination takes place. In other words, the material is invisible until it’s illuminated by a light with a matching spectrum.

Usage

In the global section of your material shader type…

spectrum [value]

Parameters

• [value] - an single digit value that defines the spectrum.

Notes

Light spectrum is defined within light shaders using the same keyword. For example the following material and light shader use the same spectrum…

textures/hell/pentastic1_spectrum
{
        qer_editorimage textures/hell/pentastic1.tga
        DECAL_MACRO
        noShadows

        blend   diffusemap
                map textures/hell/pentastic1.tga

        }
     
}
