# Configure the size and density of Adaptive Probe Volumes
|
||
|
|
|
||
|
|
Refer to [Understanding Adaptive Probe Volumes](probevolumes-concept.md) for more information about how Adaptive Probe Volumes work.
|
||
|
|
|
||
|
|
## Change the size
|
||
|
|
|
||
|
|
To ensure HDRP considers static geometry from all loaded scenes when it places Light Probes, set **Mode** to **Global** in the Adaptive Probe Volume Inspector window so the Adaptive Probe Volume covers the entire scene.
|
||
|
|
|
||
|
|
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](probevolumes-inspector-reference.md) for more information.
|
||
|
|
- To exclude certain GameObjects when HDRP calculates Light Probe positions, enable **Override Renderer Filters**. For more information about Layers, refer to [Layers and Layer Masks](https://docs.unity3d.com/Manual/layers-and-layermasks.html).
|
||
|
|
|
||
|
|
You can use multiple Adaptive Probe Volumes in a single scene, and they can overlap. However in a Baking Set, HDRP creates only a single Light Probe structure.
|
||
|
|
|
||
|
|
## 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](probevolumes-inspector-reference.md), 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](probevolumes-lighting-panel-reference.md), 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 terrain is detailed but less important than your main scenery or characters, you can do the following:
|
||
|
|
|
||
|
|
1. Put terrain on its own [Layer](https://docs.unity3d.com/Manual/layers-and-layermasks.html).
|
||
|
|
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 Mask** 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.
