Hi,
have a problem with my installation of Unreal Engine 4. I want to make vulkan work, so I followed this tutorial :

So I took the Engine From the release branch from Git Hub, and tried to build it. Everything works fine except the VulkanRHI.dll. Here is my error :
A:\Program Files (x86)\Epic Games\UnrealEngine-release\Engine\Source\Runtime\VulkanRHI\Private\VulkanShaders.cpp(13): fatal error C1083: Impossible d’ouvrir le fichier include : ‘vulkan/icd-spv.h’ : No such file or directory
11>ERROR : UBT error : Failed to produce item: A:\Program Files (x86)\Epic Games\UnrealEngine-release\Engine\Binaries\Win64\UE4Editor-VulkanRHI.dll

The file exist in : A:\Program Files (x86)\Epic Games\UnrealEngine-release\Engine\Source\ThirdParty\Vulkan\Windows\Include\vulkan

So where is the bug ? Why it doesn’t detect this file ? Is that come from VS 2015, like a variable missing ?

Thanks in advance.

So I write an absolute path after the include in the VulkanShader.cpp file and it works ! But still, why it didn’t works the first time ?

Did you install the Vulkan SDK by any chance? Probably it is messing with the paths. Uninstall the SDK and revert the header include to its original state and try again. It should work without having the absolute path.

had exactly the same problem. thanks for sharing the trick with the absolute path.
