vkGetRayTracingShaderGroupStackSizeKHR

To query the pipeline stack size of shaders in a shader group in the ray tracing pipeline, call:

VkDeviceSize vkGetRayTracingShaderGroupStackSizeKHR(
    VkDevice device,
    VkPipeline pipeline,
    uint32_t group,
    VkShaderGroupShaderKHR groupShader);

• device is the logical device containing the ray tracing pipeline.
• pipeline is the ray tracing pipeline object containing the shaders groups.
• group is the index of the shader group to query.
• groupShader is the type of shader from the group to query.

The return value is the ray tracing pipeline stack size in bytes for the specified shader as called from the specified shader group.
