Steps to reproduce:

1. Open the attached project.

2. Open the Assets/Scenes/SkyOcclusion.unity scene

3. Look at the GameView with the Camera in the scene

4. Using the Rendering Debugger, Display the Bricks in the Probe Volume section 

5. Notice the seams between the purple and orange bricks

6. In the Lighting Window, and Adaptive Probe Volume tab, disable SkyOcclusion and Generate Lighting

7. Notice that the seams are gone

8. Open the Assets/Scenes/ShadowMask.unity scene

9. Look at the GameView with the Camera01 in the scene

10. Using the Rendering Debugger, Display the Bricks in the Probe Volume section 

11. Notice the seams between the purple and orange bricks

12. Look at the GameView with the Camera02 in the scene

13. We are now seeing the realtime shadow, since we moved closer to the scene. Notice how the seams are gone, because we are only looking at baked indirect lighting, the anti-seam mechanism works for this.

Actual results: 
A clear seam is visible between subdivision levels when looking at ShadowMask and SkyOcclusion:

ShadowMask :

Expected results: 
ShadowMask and SkyOcclusion data should be interpolated between subdivision levels, creating a smooth transition
When only using Baked Indirect, the data is interpolated : !image-2024-09-25-18-06-50-056.png|thumbnail!
