{{code|env_godrays_controller}} is a point entity available in {{bms|4}} since [https://steamcommunity.com/games/362890/announcements/detail/75795300358700519  Crossfire Update] (22 december 2015 year) and removed in [https://store.steampowered.com/news/app/362890/view/4041374038285692702 24 november 2017 year update]. This entity controls [https://en.wikipedia.org/wiki/Crepuscular_rays Crepuscular Rays], the first version of godrays effect before the november update. The november update brought [[newLight_Point|local point]] and [[newLight_Dir|sun]] new lights (also with [[newLight_Spot|new spot light]] which don't support godrays), this made [[env_godrays_controller]] with crepuscular rays useless, this is why it was removed. However, it is still not removed from the [[FGD]] file, you also still can choose the crossfire update in beta branches list.
