Hey this is a quick relighting of the swimming pool made in Unreal 4.26 during 2 or 3 evenings.
As always I made differents lighting one for a clear day and the other for a sunset.
I used the raytrace for reflections and some shadows, the lighting is baked and I used SSGI to complete it.
(You can find the project on the Unreal Marketplace: https://bit.ly/2QJgSzl )
