MicroAVL - Unity Volumetric Lights

Check out the complete Analytical Volumetric Lighting package with multiple volumetric shapes, clustered rendering and optimizations, frame upscaling, and much, much more on the Asset Store!

MicroAVL is a shader intended to replicate the behavior of the volumetric lighting based on the analytical approach. Instead of estimating air light integrals with raymarching, they are calculated precisely.

Main Features 🌟

• No Draw Distance Limit: Draw distance is not limited compared to the raymarching solutions due to the analytical light equation solution. Render both close and far lights with the same fidelity at the same time.
• No Noise Filtering: As raymarching is not being used, lights produce highly accurate values with no filtering required. This deeply improves lighting fidelity with no performance trade.
• Both Deferred and Forward rendering are supported!
• Both Perspective and Orthographic camera projections are natively supported!
