HDRP Shadow Manager (HSM) is a plug-and-play tool that optimizes shadows for Spot- and Pointlights in Unity's High Definition Render Pipeline (HDRP). It ensures shadows are smart, responsive, and efficient, making it ideal for cinematic experiences and open-world games. HSM is battle-tested and used in real projects, and it's easy to set up with a one-click process. You can fine-tune shadow settings using intuitive sliders, and it supports static vs. dynamic shadow behavior. With HSM, you can increase realism, reduce draw calls, and maximize FPS.
HSM dynamically adjusts shadow settings based on distance to the camera, on-screen vs. off-screen visibility, and light range. It determines whether shadows should be rendered in real-time, cached, or completely disabled, depending on performance and visuals. You can control real-time and cached shadows using distance multiplier sliders. HSM also decides the resolution of shadows in real-time mode using the Shadow LOD System.
