I finally decided to learn Unreal Engine 5. Found a great tutorial series, Spent 3 days, boom! The series was perfectly explained and UE5 and Megascans just make it so easy to just get started!
I build the ground/rocks using Megascan. Modeled/textured the Pillers and Mountains with C4D, Zbrush, and substance painter. The cloak was done in Marvelous designer. Final comping work done in After effects.
