Forest River Valley - Unreal Engine Procedural Biome (PCG) study
Hello everyone! I have been studying the use of Unreal Engine's PCG biome recently. I have always used Houdini for procedural generation. This is my first time using Unreal Engine's PCG framework to make procedural biomes. This time I also tried multiple lighting effects in the environment and used data layers to switch between multiple lights.I learned a lot in the process. I hope you like it!

Elements used by PCG
For vegetation such as creepers that need to hang upside down on rocks, you need to reset WorldRayHit's RayOrigin (use BoundsCenter instead) and RayDirection (0,0,-1)->(0,0,1)
