Unreal Engine 4 - improve your lighting with RTXGI

William Faucher 2021-10-29 10:33 tutorial  > Unreal Engine  > modeling

In this tutorial William Faucher talks about Nvidia's RTXGI plugin.

This is a relatively new lighting method that completely leapfrogs the default Raytraced Global Illumination options in UE4 / Unreal Engine 4.

While Unreal Engine 5 has Lumen, RTXGI is a worthy competitor. In this video we cover how to set up the plugin, how to use RTXGI, how it works, as well as a few other quality of life settings that are really good to know about. You DON'T need an RTX GPU for this to work. But it should go without saying that you need to enable raytracing in your project settings for this to work.

Console Commands for RTXGI:
r.GlobalIllumination.ExperimentalPlugin 1
r.RTXGI.DDGI 1
