C Specification

To specify which aspects of an input attachment can be read, add a VkRenderPassInputAttachmentAspectCreateInfo structure to the pNext chain of the VkRenderPassCreateInfo structure:

The VkRenderPassInputAttachmentAspectCreateInfo structure is defined as:

typedef struct VkRenderPassInputAttachmentAspectCreateInfo {
    VkStructureType                            sType;
    const void*                                pNext;
    uint32_t                                   aspectReferenceCount;
    const VkInputAttachmentAspectReference*    pAspectReferences;
} VkRenderPassInputAttachmentAspectCreateInfo;

or the equivalent

typedef VkRenderPassInputAttachmentAspectCreateInfo VkRenderPassInputAttachmentAspectCreateInfoKHR;


  • sType is the type of this structure.

  • pNext is NULL or a pointer to an extension-specific structure.

  • aspectReferenceCount is the number of elements in the pAspectReferences array.

  • pAspectReferences is a pointer to an array of aspectReferenceCount VkInputAttachmentAspectReference structures containing a mask describing which aspect(s) can be accessed for a given input attachment within a given subpass.


An application can access any aspect of an input attachment that does not have a specified aspect mask in the pAspectReferences array. Otherwise, an application must not access aspect(s) of an input attachment other than those in its specified aspect mask.

Valid Usage (Implicit)

  • pAspectReferences must be a valid pointer to an array of aspectReferenceCount valid VkInputAttachmentAspectReference structures

  • aspectReferenceCount must be greater than 0
