| The **Diffuse Probe Grid** component creates a volume of light probes that provide diffuse global illumination (GI) within the specified area. Each probe in the volume uses real-time ray tracing to capture the *irradiance*, or surrounding diffuse light environment. Real-time ray tracing casts several hundred rays in different directions around each probe. The probe stores lighting information at each point of intersection between the ray and the mesh. Then, it creates an irradiance texture out of the ray traced data and applies the texture to each mesh. | |||

stores lighting information at each point of intersection between the ray and the mesh
What mesh? Any mesh contained within the specified area? Might improve clarity if you can be more specific here.

I think mesh may refer to the surrounding geometry? Or just the geometry within the volume.
@dmcdiarmid-ly Can you specify?

I believe the meshes that the rays intersect with refer to all of the geometry in the level that are in the direction of the ray.
Hopefully this is more clear. I updated the sentence to:
At each point of intersection between the ray and the surrounding geometry, the probe stores lighting information.
| | **Y-Axis** | The amount of space between probes along the y-axis. The space must be within the Box Shape component's dimension along the y-axis. | `0.0` to the Box Shape component's `Dimensions`-`Y` property. | The lowest value from the Box Shape component's `Dimensions`-`XYZ` property. | | ||
| | **Z-Axis** | The amount of space between probes along the z-axis. The space must be within the Box Shape component's dimension along the z-axis. | `0.0` to the Box Shape component's `Dimensions`-`Z` property. | The lowest value from the Box Shape component's `Dimensions`-`XYZ` property. | |

The default info doesn't seem right. I tried this and the default values for each axis were 2.0 meters, even though the lowest value of the box shape was 8.0 meters.

After reviewing this, you're right the default value is 2.0 meters. I believe what I was observing may have been the probe spacing values updating when I update the mesh.
