Shader Error, during unity project build

[AlexandrZabolotny]

Hello! Step 20 from documentation. We check Environments, Vehicles, choose folder, then click build button, then we get error in console

Shader error in 'DiffuseDenoiser.compute': failed to open source file: 'Packages/com.unity.render-pipelines.high-definition/Runtime/RenderPipeline/Raytracing/HDRayTracingManager.cs.hlsl' at kernel BilateralFilterColor at Packages/com.unity.render-pipelines.high-definition/Runtime/RenderPipeline/Raytracing/Shaders/ShaderVariablesRaytracing.hlsl(1) (on d3d11)

@AlexandrZabolotny Hello. What OS are you using? If you are on Linux, are you using Vulkan, not OpenGL? What Unity version and what LGSVL Simulator version are you using? Did you install both Windows and Linux build support in UnityHub? Does your GPU support d3d11? One solution is to delete the Library folder that unity creates in Simulator root, open Unity editor and let it recreate it. Also, be sure to build one asset at a time to see if a certain asset is causing and issue.

@EricBoiseLGSVL, Ubuntu 16.04 How can i check what i am using(Vulcan or OpenGL)?

Simulator release 2020.03

How can i check d3d11 support?

You can search for "Vulcan" in: .config/unity3d/LG Silicon Valley Lab/LGSVL Simulator/Player.log.

You should see something like the following:

Vulkan API version 1.1.0 (1.1.119 supported by driver)
Vulkan vendor=[NVIDIA] id=[10de]
Vulkan renderer=[GeForce RTX 2070 with Max-Q Design] id=[1f10]

Simulator release 2020.03 How can i check d3d11 support? That's a Windows thing but will indicate whether your GPU has the needed hardware support; knowing which GPU you have would be helpful -- and that should appear as the Vulkan renderer in Player.log as noted above.

@lemketron,

Vulkan API version 1.1.0 (1.1.95 supported by driver)
Vulkan vendor=[NVIDIA] id=[10de]
Vulkan renderer=[GeForce RTX 2070] id=[1f10]
Vulkan device type 2
Vulkan driverversion=[0x6895c040] uint=[1754644544]
Vulkan PSO: cache data not found [path=/tmp/LG Silicon Valley Lab/LGSVL Simulator/vulkan_pso_cache.bin]

...

@AlexandrZabolotny That looks fine. Did you delete the Library folder and re-compile shader code?

I see error from Book of the Dead demo:
