I cloned the NativeRenderingPlugin project from GitHub, modified the #define SUPPORT\_VULKAN 0 to 1 in PlatformBase.h file, compiled RenderingPlugin.dll based on Vulkan SDK 1.3 in Visual Studio 2022 Community, and set the dll file to load on startup in the Unity project. However, every time I open the project it crashes. After multiple tests, I found that it always crashes when executing Hook\_vkCreateInstance() function in RenderAPI\_Vulkan.cpp, even after switching to different Unity versions.
When checking the Editor.log file, the log for Unity 2022.3 is

I hope to customize vkCreateinstance and vkCreateDevice. How can I solve the crash issue?

I met the same problem when I set the NativeRenderPlugin to preload. I have the same requirement to customize vkCreateinstance and vkCreateDevice. And I try to enable Validation layer in VkInstanceCreateInfo when calling vkCreateinstance but nothing written.

I also have the same problem.I want to know the solution too.

> Hi @florianpenzkofer , I’m trying to get the vkCreateDevice hook working, but it seems like the device has already been created by the time the plugin is loaded. if (s\_Graphics-\>GetRenderer() == kUnityGfxRendererNull) { extern void RenderAPI\_Vulkan\_OnPluginLoad(IUnityInterfaces\*); RenderAPI\_Vulkan\_OnPluginLoad(unityInterfaces); } At this point, s\_Graphics-\>GetRenderer() returns kUnityGfxRendererVulkan, and even if I force it into RenderAPI\_Vulkan\_OnPluginLoad, the vkCreateDevice hook is not c…

When I upgraded my graphics card from 1060 to 2060, the problem was solved. So, could this be a bug in the graphics card driver?
