To query the opaque capture data of shader groups in a ray tracing pipeline, call:
// Provided by VK_KHR_ray_tracing_pipeline VkResult vkGetRayTracingCaptureReplayShaderGroupHandlesKHR( VkDevice device, VkPipeline pipeline, uint32_t firstGroup, uint32_t groupCount, size_t dataSize, void* pData);
deviceis the logical device containing the ray tracing pipeline.
pipelineis the ray tracing pipeline object containing the shaders.
firstGroupis the index of the first group to retrieve a handle for from the VkRayTracingPipelineCreateInfoKHR::
groupCountis the number of shader handles to retrieve.
dataSizeis the size in bytes of the buffer pointed to by
pDatais a pointer to a user-allocated buffer where the results will be written.
Once queried, this opaque data can be provided at pipeline creation time
(in a subsequent execution), using
as described in Ray Tracing Capture Replay.

The capture replay handle remains bitwise identical for any

Group indices are assigned as-if the pipeline was created without
