# VkPhysicalDeviceDynamicRenderingUnusedAttachmentsFeaturesEXT(3) Manual Page

## Name

VkPhysicalDeviceDynamicRenderingUnusedAttachmentsFeaturesEXT - Structure describing the dynamic rendering unused attachment features that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceDynamicRenderingUnusedAttachmentsFeaturesEXT` structure is defined as:

    // Provided by VK_EXT_dynamic_rendering_unused_attachments
    typedef struct VkPhysicalDeviceDynamicRenderingUnusedAttachmentsFeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           dynamicRenderingUnusedAttachments;
    } VkPhysicalDeviceDynamicRenderingUnusedAttachmentsFeaturesEXT;

## Members

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.

## Description

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.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceDynamicRenderingUnusedAttachmentsFeaturesEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_DYNAMIC_RENDERING_UNUSED_ATTACHMENTS_FEATURES_EXT`
