CryZENx has released a new video for their Unreal Engine 5 fan-made remake of The Legend of Zelda: Ocarina of Time. This video showcases the visual improvements that Lumen brings. In addition, it demonstrates the territory of the Kokiri Forest.
The video starts with a comparison with/without Lumen. From what we can see, Lumen brightens the image. It also causes light to bounce off surfaces. Then, at 2:23, CryZENx shows the areas of the Kokiri Forest.
