Creating any 3D Environment is a complex and time-consuming process, especially when it comes to the amount of detail needed. I start from creating a terrain and then adding elements like vegetation, rocks, sky, wind, fog ecc, lightning is very important for realism, i then create my camera angles and animate them. Color grading and 3dlut are used to create a cinematic look. Some of the softwares i use are Unreal Engine 4 - Speedtree - Quixel Mixer and Megascans - Substance Painter and Source - World Creator 2 - Premiere or Davinci Resolve. All the rest is just in my imagination.
