Probe placement fails when baking Adaptive Probe Volumes on Vulkan
Reproduction steps:
1. Open the attached “IN-136557” project
2. Open the “Scenes/SampleScene” Scene
3. Open the Project Settings window (Edit > Project Settings)
4. In the “Player” tab, make sure the “Graphics API for Windows” is set to “Direct3D11”
5. Open the Lighting window (Window > Rendering > Lighting)
6. Press the “Generate Lighting” button
7. Open the Rendering Debugger window (Window > Analysis > Rendering Debugger)
8. In the “Probe Volumes” tab, enable “Display Bricks” under “Subdivision Visualization” category
9. Observe the Scene View
10. Repeat 3-9 steps, but change the “Graphics API for Windows” to “Vulkan”
Actual result: After baking lighting on Vulkan, Adaptive Probe Volumes place probes sparsely as if scene geometry is not detected
Expected result: After baking lighting on Vulkan, Adaptive Probe Volumes place probes densely around scene geometry, matching DirectX 11 behavior
Reproducible with: 2023.1.0a2, 6000.0.71f1, 6000.3.12f1, 6000.4.1f1, 6000.5.0b1, 6000.6.0a1
Reproducible on: Windows 11 (RX 6800 XT)
Not reproducible on: Windows 11 (RTX 3080)
Note:
- The issue only reproduces using Vulkan Graphics API. Does not reproduce using DX11 or DX12
