Here's a personal project inspired by a challenge from my fiancé that I created in UE5 early access, without the use of external programs. All of the rock based assets in the scene are Megascans and were added via the built in Quixel Bridge. Other assets were built in engine using the modeling tools.
Concept art used for initial inspiration: https://www.artstation.com/artwork/VLxBR
The camping assets are from Dekogon's pack on the Unreal Marketplace, which can be found here: https://www.unrealengine.com/marketplace/en-US/product/camping-and-outdoor-adventure-vol
