Configure the size and density of Adaptive Probe Volumes

Refer to Understanding Adaptive Probe Volumes for more information about how Adaptive Probe Volumes work.

A collection of light probes arranged within a given space can improve lighting on moving objects and static LOD scenery within that space. More info

In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info

.

You can also do one of the following in the Inspector of an Adaptive Probe Volume, to set the size of an Adaptive Probe Volume:

  • Set Mode to Local and set the size manually.
  • Set Mode to Local and select Fit to all Scenes, Fit to Scene, or Fit to Selection. Refer to Adaptive Probe Volume Inspector reference for more information.
  • To exclude certain GameObjectsThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info

    when URP calculates Light Probe positions, enable Override Renderer Filters. For more information about Layers, refer to Layers and Layer Masks.

You can use multiple Adaptive Probe Volumes in a single scene, and they can overlap. However in a Baking Set, URP creates only a single Light Probe structure. trouble

Resize

To resize the Adaptive Probe Volume, use one of the handles of the box gizmoA graphic overlay associated with a GameObject in a Scene, and displayed in the Scene View. Built-in scene tools such as the move tool are Gizmos, and you can create custom Gizmos using textures or scripting. Some Gizmos are only drawn when the GameObject is selected, while other Gizmos are drawn by the Editor regardless of which GameObjects are selected. More info

Adjust Light Probe density

You might need to do the following in your project:

  • Increase Light Probe density in highly detailed scenes or areas such as interiors, to get a good lighting result.
  • Decrease Light Probe density in empty areas, to avoid those areas using disk space and increasing bake time unnecessarily.

In the Inspector for an Adaptive Probe Volume, enable and adjust Override Probe Spacing to set a minimum and maximum density for the Light Probes in the Adaptive Probe Volume.

The values can’t exceed the Min Probe Spacing or Max Probe Spacing values in the Probe Placement section of the Adaptive Probe Volumes panel, so you might need to adjust these values first.

You can also add local Adaptive Probe Volumes in different areas with different Override Probe Spacing values, to control Light Probe density more granularly. For example, in empty areas, add a local Adaptive Probe Volume with a higher Override Probe Spacing minimum value, to make sure Light Probes have a lower density in those areas.

If you increase Light Probe density, you might increase bake time and how much disk space your Adaptive Probe Volume uses.

Decrease Light Probe density for terrain

Because terrainThe landscape in your scene. A Terrain GameObject adds a large flat plane to your scene and you can use the Terrain’s Inspector window to create a detailed landscape. More info

is detailed but less important than your main scenery or characters, you can do the following:

  1. Put terrain on its own LayerLayers in Unity can be used to selectively opt groups of GameObjects in or out of certain processes or calculations. This includes camera rendering, lighting, physics collisions, or custom calculations in your own code. More info

    .
  2. Surround the terrain with an Adaptive Probe Volume.
  3. In the Inspector for the Adaptive Probe Volume, enable Override Renderer Filters, then in Layer MaskA value defining which layers to include or exclude from an operation, such as rendering, collision or your own code. More info

    select only your terrain Layer.
  4. To adjust Light Probe density to capture more or less lighting detail, enable Override Probe Spacing and adjust the values.
