    This product contains an assortment of Unreal Engine assets which can be imported into a pre-existing project of your choice.

Different light sources, lenses, and environmental conditions produce different forms of flares, which can significantly increase the visual impact of the picture, and sometimes bring a specific atmosphere.

This package provides some common lens flare shapes and some creative patterns to make your light source look more realistic or interesting. You can apply them to all kinds of emissive lights, like stars, sun, moon, streetlights, car lights, particles, lasers, etc...

Usage Tips:

  • Just change your Post Process Volume's bloom method to "convolution" and set "Convolution Kernel" to one of these kernel textures.
  • Adjust scale and boost parameters to the look you want. 
  • UE5 has an additional parameter called "Convolution Scatter Dispersion", it allows you adjust bloom intensity more dynamically.
  • Distant lights may not work very well when your project is using TAA, you can change "Anti-Aliasing method" to "FXAA" in project settings. 
  • Check out the overview and demo map to see the thumbnails and results.
