I want to combine the images of my external Vulkan renderer with Unitys frame. So they should render simultaneously and when GL.IssuePluginEvent() is called, both frames will be used in a separate rendering process.
For now I wait on my “external” renderer via a fence, is there a way to make Unity wait on a semaphore which was imported from another Vulkan instance? Since I don’t submit Unitys Vulkan queue myself I don’t see a way for now.
