Weather Maker 2.3 introduces volumetric lighting. Watch your lights really come alive in full 3D with realistic light scattering and attenuation. This even works in VR! Get Weather Maker here: https://www.assetstore.unity3d.com/en...
Remember to add your lights to the light manager and turn on "EnableFogLights" on the fog script to get them showing up.
The Weather Maker volumetric light shader is highly optimized with no branching and minimal ray tracing.
Thanks for watching!
