Hi, I’m encountering in the native plugin.
I find out that in IUnityGraphicsVulkan.h
There are two type of Vulkan in IUnityInterfcaes:

  1. IUnityGraphicsVulkanv2
  2. IUnityGraphicsVulkan

I have searched for the document(There are no document about this) and the code inside IUnityGraphicsVulkan.h, but I can’t find the answer.

Not sure if this helps but release notes says:
“XR: Added: Added IUnityGraphicsVulkanV2 plugin interface to add support for chaining vulkan initialization intercepts.”

Ticket number is 1349908, but it seems to be private.
