UPDATE 5/05/2021: After watching Maria's relighting on my scene I decided to give it another go and finally put it to sleep, This version is closer to the one that Maria used with the flag, the grass, and the water. I also want to thank Mara as well for her intervention which I think is fantastic. Also thank you Tyler Smith for the awesome waterfall tutorial which I used in this project.
Everything was rendered inside Unreal using the Nvidia RTX Branch all aspects of the environment were done by me except for some of the Megascans vegetation and the Butterfly market place asset made by Dragon's Soul (Thanks a lot Maria for all your advice and giving me inspiration to finally finish this piece!)

This was a personal project. I was really heavily inspired by the Buddhist temples built inside caves, especially the Khao Luang Cave Temple. Everything was sculpted in Zbrush (including the Octophant that was on the previous post) and textured using substance painter. Ground textures were made inside Substance Designer.
