This scene was created in Unreal Engine 4 for light studies. My goal was to achieve photorealism with natural lighting conditions. The building model is an adaptation of an Evermotion ArchExterior model for 3D Studio Max. I created the foliage in SpeedTree and you can see their creation process in other jobs in my gallery.
And this is a WIP solution to bring those interactive scenarios to mobile world. More on that later =)
