Mastering Lighting in Unreal Engine | Static, Movable & GPU Optimization Techniques in Unreal | 01

If you want to mastering lighting in Unreal Engine - watch this series!
In the first video - Unreal Engine's lighting mechanics, detailing three primary light types (static, movable, and stationary) and their GPU demands. It explores five light sources including directional, point, spotlight, rectangular, and skylight. The video covers practical aspects such as HDRI backdrops, sun and sky settings, and a comparison of built-in and third-party plugins for light baking. The video also demonstrates how to adjust lighting settings, the impact of virtual textures, and optimizing light quality and performance in Unreal Engine projects.

Hey! Great video. Help me understand though, what's the reason for using baked light in 2023 UE5.3 instead of real time lumen? When I try to Google if there is any advantages to using baked light I only end up on really old articles.. Thanks in advance!

In short, baking is used for interiors and lumen is used for exteriors. In our chat you can ask questions to subscribers) t.me/+jZg5DzHMR81lYzgy
