//decrease to gain performance
//but keep in mind effect will start to break
//revealing the squarish nature of the lightshafts
//so increasing would be a better idea
//but at the exchange of performance

//Mornings are more powerful already
//so I decreased it
//noon is for noon and moon is for nights
//you may get shafts for lightnings and moon maybe

//edit for light colorness, lower the value for desaturated colors...
