Have you heard of ambience videos? If you haven't, they're similar to those Yule Log videos that come out around Christmas. The difference is that these types of ambience videos have lush or even fantastical environments that are made to emphasize the environmental sounds. I run a YouTube channel for these type of videos that I create using Unreal Engine 5. I use assets I've either made myself or gotten from the marketplace/Megascans.
Software used: Unreal Engine 5, Blender 3.0+, DaVinci Resolve
This was scene was entirely created with marketplace assets
This scene uses an early version of my snowy mountain cabin. I used a blueprint from the Unreal marketplace to get dynamic northern lights in the sky.
I try not to spend more than 2-3 days working on any of these scenes. Most of my time is spent working on the lighting since that is very important in ambience videos. This was another scene that uses marketplace assets.
