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. VkPhysicalDeviceDynamicRenderingUnusedAttachmentsFeaturesEXT can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.
