// This defines a custom VolumeComponent to be used with the Core VolumeFramework
// (see core API docs https://docs.unity3d.com/Packages/com.unity.render-pipelines.core@latest/index.html?subfolder=/api/UnityEngine.Rendering.VolumeComponent.html)
// (see URP docs https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@latest/index.html?subfolder=/manual/Volumes.html)
//
// After implementing this class you can:
// * Tweak the default values for this VolumeComponent in the URP GlobalSettings
// * Add overrides for this VolumeComponent to any local or global scene volume profiles
//   (see URP docs https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@latest/index.html?subfolder=/manual/Volume-Profile.html)
//   (see URP docs https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@latest/index.html?subfolder=/manual/VolumeOverrides.html)
// * Access the blended values of this VolumeComponent from your ScriptableRenderPasses or scripts using the VolumeManager API
//   (see core API docs https://docs.unity3d.com/Packages/com.unity.render-pipelines.core@latest/index.html?subfolder=/api/UnityEngine.Rendering.VolumeManager.html)
// * Override the values for this volume per-camera by placing a VolumeProfile in a dedicated layer and setting the camera's "Volume Mask" to that layer
//
// Things to keep in mind:
// * Be careful when renaming, changing types or removing public fields to not break existing instances of this class (note that this class inherits from ScriptableObject so the same serialization rules apply)
// * The 'IPostProcessComponent' interface adds the 'IsActive()' method, which is currently not strictly necessary and is for your own convenience
// * It is recommended to only expose fields that are expected to change. Fields which are constant such as shaders, materials or LUT textures
//   should likely be in AssetBundles or referenced by serialized fields of your custom ScriptableRendererFeatures on used renderers so they would not get stripped during builds
