Shadows Midtones Highlights
The Shadows Midtones Highlights effect separately controls the shadows, midtones, and highlights of the render. Unlike Lift, Gamma, Gain, you can use this effect to precisely define the tonal range for shadows, midtones, and highlights.
Using Shadows Midtones Highlights
Shadows Midtones Highlights uses the Volume framework, so to enable and modify the shadows, midtones, or highlights of the render, you must add a Shadows Midtones Highlights override to a Volume in your Scene. To add Shadows Midtones Highlights to a Volume:
- In the Scene or Hierarchy view, select a GameObject that contains a Volume component to view it in the Inspector.
- In the Inspector, go to Add Override > Post-processing and select Shadows Midtones Highlights. HDRP now applies Shadows Midtones Highlights to any Camera this Volume affects.
API
To access and control this override at runtime, use the Volume scripting API. Because of how the Volume system works, you edit properties in a different way to standard Unity components. There are also other nuances to be aware of too, such as each property has an overrideState. This indicates to the Volume system whether to use the property value you set, or use the default value stored in the Volume Profile. For information on how to use the API correctly, see Volume scripting API.
