Realistic Lens Flare

Description

A quick test project I made to generate lens flares, the kind of lens effect which would be visible when you point a camera at a bright light source like the sun. The end result is a quite nice-looking effect. The effect is composed of many individual lens flare elements. I made two of the lens flare textures using external image editing software, each one is a simple shape colored white with a radial gradient ranging from opaque at the edges to partially transparent at the center. More transparency is added by the project itself. This is a clone-based method, which means each lens element is a clone (A stamp-based version is perfectly doable, though). The clone is assigned a random size, position factor, shape, and transparency. There are 30 clones in total, though this can be changed in the code depending on how many lens elements are needed. The lens elements' positions are all multiples of the sun position. Everything is done in 2D, but this can be applied to a 3D project if Sun X and Sun Y are set to the projected coordinates of the sun. This project doesn't lag very much, but it does look smoother on TurboWarp with these settings: https://turbowarp.org/666704223?hqpen&fps=60&limitless Updated 16 April 2022 - Added exposure adjustment, where the background darkens when looking directly at the sun. Changed the sun streaks to make them fade in when looking directly at the sun.
