ray_tracing_motionblur: Validation error

[kyamant]

Using Vulkan sdk 1.3.216, RTX 3070Ti (516.94) on windows 10, I am getting the following message:

ERROR: VUID-VkAccelerationStructureGeometryTrianglesDataKHR-pNext-pNext
 --> Validation Error: [ VUID-VkAccelerationStructureGeometryTrianglesDataKHR-pNext-pNext ] Object 0: handle = 0x27b882ea480, type = VK_OBJECT_TYPE_DEVICE; | MessageID = 0xf69d66f5 | vkGetAccelerationStructureBuildSizesKHR: value of pInfos[0].pGeometries[0].geometry.triangles.pNext must be NULL.

The Vulkan spec states: pCode must not declare any SPIR-V extension that is not supported by the API, as described by the Extension section of the SPIR-V Environment appendix (https://vulkan.lunarg.com/doc/view/1.3.216.0/windows/1.3-extensions/vkspec.html#VUID-VkShaderModuleCreateInfo-pCode-04146)

Output seems ok:

Thanks @kyamant for reporting this. The NVIDIA motion blur extension is not integrated in the Khronos validation layer, and new validation errors are showing up. They are harmless and can be ignored by adding the following to main(), next to the other ignore debug message.

  vkctx.ignoreDebugMessage(0xf69d66f5);  // Value of pInfos[0].pGeometries[0].geometry.triangles.pNext must be NULL
  vkctx.ignoreDebugMessage(0xd80a42ae);  // SPIR-V Extension (SPV_NV_ray_tracing_motion_blur)

I'll make an update soon to correct this.
