How do i fix the sunrays effect?

I know this does not really pertain to lua that much but I'm having an issue with the sunrays effect in studio. I have it in studio under lighting with the settings up to the max. Furthermore, the studio rendering settings are at level 21 for bothe edit and quality. I even tried changing the Graphics settings to Direct3D11 but nothing has worked for me. I also tried reseting the graphic settings and then putting it back at lvl 21. Ive tested it both in studio and in game and it has shown no results. At this point, I don't know what to do. Does anyone have any ideas on how I can fix this? I've even tried sing code and it hasn't made any changes?

local sunRays = Instance.new("SunRaysEffect",game.Lighting)

sunRays.Intensity = .25
sunRays.Spread = 1
