    public:

        __property D3DVALUE Falloff = { read=FGetFalloff, write=FSetFalloff, nodefault };




    -= Go to the TD3DLight description =-    TD3DLIGHT::FALLOFF   [ component property ]

    • Description

        The Falloff property contains a D3DVALUE representing the decrease in illumination from a spotlight's umbra, defined by the Theta property, and the outer edge of the penumbra, defined by the Phi property.

        A value of 1.0 will result in a linear falloff from the umbra to the penumbra.
        Values greater than 1.0 will cause the light to fall off quickly at first and then fade slowly to the penumbra while a value less than 1.0 will create the opposite effect.
        The effect of non 1.0 values is subtle and affects performance a little, thus a 1.0 value is generally reccomended.
