Regression
Yes
The "Camera.Render" hangs the process of geometry baking in the textures when using HDRP
How to reproduce:
1. Open the “ReproCameraRender“ project
2. Open the “OutdoorsScene“
3. Open the “Assets“ folder in the Project window
4. Open the “New Impostor“ asset in the Inspector window
5. Click on the “Build“ button
Expected result: The baking process will take only a few minutes
Actual result: The baking process may hang or take a really long time (up to 1H. I recomend downscaling the settings in the builder so you can be at ~5min instead for testing)
Reproducible with: -2023.2.0a6,- 6000.0.11f1
Not reproducible with: 2021.3.40f1, 2022.3.38f1, 2023.2.0a5
Note: 2023.2.0a6 regression was causing by something else solve by some times. It is a different issue.
Producible with: DX12 - Split
Not reproducible with: DX11, DX12 - Legacy, DX12 - Native
Reproducible on: Windows 10 Pro (22H2)
Not reproducible on: macOS 14.5 (Intel)
Note: if the baking succeeds just click on the “Clear“ button on the “New Impostor“ asset, to clear the pre-baked data
Through first investigation, it seams that in this usage, something prevent the m_DependentFenceCreates in GPUFenceDependencyChecker::RemoveDependencyFromAllWaitingFences to forget element. This is the best explanation for exponentially increasing time (see attached images from Superluminal)
