This is an example of Godot's volumetric fog capabilities with the Vulkan renderer.

Showcased features are:

• Positive/negative density volumes that affect albedo (incoming light) and emission.
• Box/ellipsoid shapes, height falloff, and density modulation using a 3D texture.
• Temporal reprojection for greater stability and avoiding flickering.
  • The difference is demonstrated with a moving fog volume.
• Global density adjustment. With FogVolume nodes that have a positive density, it's possible to apply volumetric fog only in specific areas.
• Custom FogVolume shader with real-time 3D noise (provided by alghost).
