Valley of a Forgotten Land is my latest environment study.
I used this environment to learn more about Unreal Engine 5's PCG (Procedural Content Generation) workflows.
Foliage was created in TreeIt which is a free alternative to Speedtree.
Terrains were created in Gaea 2 with extra sculpting done in Zbrush.
The Tower was scanned in Reality Capture and cleaned up in Zbrush and Maya.
