zh4os / Unity-Volumetric-Light

A powerful volumetric light plugin based on post-processing in Unity3D

Unity Volumetric Light

Features:

• Volumetric light in current real-time rendering could be expensive in PC and PS4, so we use downsample and jitter to optimize the performance.
• Native directional shadowmap supported.
• Cascade Directional Shadow supported.
• Mie Scattering supported.
• Height Fog Supported.

Tutorial:

• Add "VolumetricLightRenderer.cs" on scene render camera.
• Choose downsample level in "VolumetricLightRenderer.cs", for instance: x2 is half resolution, x3 is one third resolution and x4 is one quater resolution. The less resolution will cause better performance and worse quality.
• Add "VolumetricLight.cs" on the directional light.
• Enable "Hard Shadow" or "Soft Shadow" to let volumetric light component use shadowmap.
