I was curious about replicating the UE4 lens flare effect, I don't think it's good enough yet, but I'd like to hear some opinions.
Get it here:

Here it is in motion
This has been explored here before
, but I don't know if anything came out of it.
One way I'm thinking of improving it is using a single flare blurred texture and then scale it to create the other flares, this way I could have separated flare blur sizes, rather than all of them being blurred equally. Also maybe throw in some lens distortion somewhere.
