Hello developers! Today I saw one interesting thing at one of the demonstrations, namely these circles or what is it…
I really don’t know what to call it but it looks beautiful. Could you help me achieve this effect?
It’s not very similar to the built-in Sun Rays effect.
Under lighting, you can add an effect called “SunRaysEffect.” You can tweak the variables to make it look different, too.
I think this is an additional module or scripts, because Sun Rays does not have such settings.
Hey there! That’s a lens flare effect. You are correct in that this is not a built-in feature, but more in line with additional scripts.
If I remember right, the lens flare effects I’ve seen before on Roblox were created using BillboardGui’s or Beams, either can have a similar end result.
Sorry I don’t have anything to provide that can give you this effect or more info on it. I just know it’s 1000% possible 
Good luck on it!
What demonstration?, who made it? Can you ask that person?
thanks for the answer! I think someone has already done this, but if I don’t find it, I’ll try to do it myself.
I did end up finding the old leans flare effect I originally tinkered around with, credits to @Maximum_ADHD!
It does use beams as I mentioned, and seems to be more first-person oriented, has some choppiness to it in third-person.

The LENSES array is used to control the individual lenses of the effect.
* Color - The color of the lense.
* Radius - An arbitrary scaling factor for each lense.
* Distance - A value between 0 and 1 indicating the position of the lense on the screen.
( A value of 0.5 will be at the center of the screen )
( A value of 1.0 will be directly on top of the sun )
( A value of 0.0 will be on the opposite end of the screen )

I did add a fade for transparency so it’s not as 2007 looking lol it’s not a bad take on lens flare overall though.
oh thank you! I also talked to the creator of the place where there is such an effect and he told me how to do it. As soon as I test this model, I will tell you about it!
The creator of this game told me about this model that he used in this game. Link to Twitter and Model.
