GetFileSizeEx() for path ../Assets/CSO/Release/... failed with following error code: 6

[TomClabault]

I cloned the repo, made a build folder, cmake .., open the Visual Studio Solution, set Samples/ZetaLab as starting project, added a cornell box GLTF to the command line argument and built + ran the project but ended with this error (it shows up with AutoExposure... but there are a bunch of other error Windows with more files complaining):

The working directory of the project is set to be ZetaRay/bin but the folder ../Assets does not contain a Release/ folder as seems to be expected by reading the error.

My ZetaRay/Assets folder only contains:

• CornellBox/
• Font/
• Images/
• LUT/
• PsoCache/

Any ideas?

There is a cmake target called "CompileShaders" that compiles the shaders and writes the ouputs to "./Assets/CSO/Release". It should be visible in the Solution Explorer window in VS. Could you make sure it hasn't been disabled? When enabled, the build output should've contained messages such as "Compiling AutoExposure_Histogram.hlsl...".

Okay, seems to work fine now but I have to build that target manually. Maybe something is missing in the CMake?

You shouldn't need to build it manually. For me a rebuild is triggered automatically whenever there's a change in one of the shaders. Are you sure that target hasn't been unloaded? Solution Explorer should look like this:

This is what my Visual Studio looks like:

It doesn't seem like it was unloaded. I do have the option to unload it when right clicking on it.

Instead of using VS, could you run the following on the command line in a different folder?

git clone https://github.com/alipbcs/ZetaRay
cd ZetaRay
mkdir build
cd build
cmake ..
cmake --build .

I did get this kind of output this time:

 2>Compiling HLSL source file BuildLightVoxelGrid.hlsl...
  5>Compiling HLSL source file GBufferRT_Inline.hlsl...
  3>Compiling HLSL source file Display.hlsl...
  15>Compiling HLSL source file ReSTIR_PT_PathTrace_WoPS.hlsl...

The issue is specific to VS then. For some reason, VS is skipping that target even when it's loaded.

I tested with VS 2019 and VS 2022 on two different systems and it built successfully. I'm not sure what's causing it.
