Parameters

LightIndex: Zero-based index of the set of lighting parameters that are the target of this method.
bEnable: Value indicating if the set of lighting parameters are being enabled or disabled. Set this parameter to nonzero to enable lighting with the parameters at the specified index or zero to disable it.
