Unreal Engine helped keep rendering practical on an RTX 2060 while meeting the project deadline.
The first clip was rendered in Unreal Engine 4. Later shots used Cinema 4D and Redshift for the foreground elements. The landscape started with a low-resolution blockout and hills sculpted in the engine.
Vegetation was made in SpeedTree. The weeping willows used animated Alembic sequences for cinematic rendering, rather than real-time playback.
Point and directional lights were used to shape the lighting in UE4, before Lumen.
Textured cards in UE4's particle system added volumetric effects.
