The environment was made by Eugenia Lysa for SmoughTown's most recent Elden Ring Lore video.
Have a look at Godskin Temple, a highly-detailed 3D environment inspired by Elden Ring, created by Eugenia Lysa, a 3D Environment Artist whose incredible experiments with lighting in UE4 were featured here on 80 Level back in 2021.
According to the artist, the scene was commissioned by a YouTube creator SmoughTown, who used the environment for a recent Elden Ring Lore video, dedicated to the game's Gloam-Eyed Queen and The Godskins.
To create Godskin Temple, Eugenia utilized ZBrush, Substance 3D Painter, Unreal Engine, and Photoshop. You can learn more about the environment and check out more renders by visiting the author's ArtStation page.
