# Recursive Reflections
Vulkan ray tracing allows recursive calls to traceNV, up to a limit defined by `VkPhysicalDeviceRayTracingPropertiesKHR`.
Vulkan ray tracing allows recursive calls to traceRayEXT, up to a limit defined by `VkPhysicalDeviceRayTracingPropertiesKHR`.
In `createRtPipeline()` in `hello_vulkan.cpp`, bring the maximum recursion depth up to 10, making sure not to exceed the physical device's maximum recursion limit:
