VkPhysicalDeviceDynamicRenderingUnusedAttachmentsFeaturesEXT

The VkPhysicalDeviceDynamicRenderingUnusedAttachmentsFeaturesEXT structure is defined as:

typedef struct VkPhysicalDeviceDynamicRenderingUnusedAttachmentsFeaturesEXT {
    VkStructureType sType;
    void* pNext;
    VkBool32 dynamicRenderingUnusedAttachments;
} VkPhysicalDeviceDynamicRenderingUnusedAttachmentsFeaturesEXT;

This structure describes the following feature:

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• dynamicRenderingUnusedAttachments indicates that the implementation supports binding graphics pipelines within a render pass instance where any pipeline VkPipelineRenderingCreateInfo::pColorAttachmentFormats element with a format other than VK_FORMAT_UNDEFINED is allowed with a corresponding VkRenderingInfo::pColorAttachments element with an imageView equal to VK_NULL_HANDLE, or any pipeline VkPipelineRenderingCreateInfo::pColorAttachmentFormats element with a VK_FORMAT_UNDEFINED format is allowed with a corresponding VkRenderingInfo::pColorAttachments element with a non-VK_NULL_HANDLE imageView. Also a VkPipelineRenderingCreateInfo::depthAttachmentFormat other than VK_FORMAT_UNDEFINED is allowed with a VK_NULL_HANDLE VkRenderingInfo::pDepthAttachment, or a VkPipelineRenderingCreateInfo::depthAttachmentFormat of VK_FORMAT_UNDEFINED is allowed with a non-VK_NULL_HANDLE
  VkRenderingInfo::pDepthAttachment. Also a VkPipelineRenderingCreateInfo::stencilAttachmentFormat other than VK_FORMAT_UNDEFINED is allowed with a VK_NULL_HANDLE
  VkRenderingInfo::pStencilAttachment, or a VkPipelineRenderingCreateInfo::stencilAttachmentFormat of VK_FORMAT_UNDEFINED is allowed with a non-VK_NULL_HANDLE
  VkRenderingInfo::pStencilAttachment. Any writes to a VkRenderingInfo::pColorAttachments, VkRenderingInfo::pDepthAttachment, or VkRenderingInfo::pStencilAttachment with VK_NULL_HANDLE are discarded.

If the VkPhysicalDeviceDynamicRenderingUnusedAttachmentsFeaturesEXT structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceDynamicRenderingUnusedAttachmentsFeaturesEXT, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.
