VkAttachmentReference

Structure specifying an attachment reference

The VkAttachmentReference structure is defined as:

typedef struct VkAttachmentReference {
    uint32_t attachment;
    VkImageLayout layout;
} VkAttachmentReference;
  • attachment is either an integer value identifying an attachment at the corresponding index in VkRenderPassCreateInfo::pAttachments, or VK_ATTACHMENT_UNUSED to signify that this attachment is not used.
  • layout is a VkImageLayout value specifying the layout the attachment uses during the subpass.

Valid Usage

VUID-VkAttachmentReference-layout-03077

If attachment is not VK_ATTACHMENT_UNUSED, layoutmust not be VK_IMAGE_LAYOUT_UNDEFINED, VK_IMAGE_LAYOUT_PREINITIALIZED, or VK_IMAGE_LAYOUT_PRESENT_SRC_KHR

VUID-VkAttachmentReference-separateDepthStencilLayouts-03313

If the separateDepthStencilLayouts feature is not enabled, and attachment is not VK_ATTACHMENT_UNUSED, layout must not be VK_IMAGE_LAYOUT_DEPTH_ATTACHMENT_OPTIMAL, VK_IMAGE_LAYOUT_DEPTH_READ_ONLY_OPTIMAL, VK_IMAGE_LAYOUT_STENCIL_ATTACHMENT_OPTIMAL, or VK_IMAGE_LAYOUT_STENCIL_READ_ONLY_OPTIMAL,

VUID-VkAttachmentReference-synchronization2-06910

If the synchronization2 feature is not enabled, layout must not be VK_IMAGE_LAYOUT_ATTACHMENT_OPTIMAL_KHR or VK_IMAGE_LAYOUT_READ_ONLY_OPTIMAL_KHR

VUID-VkAttachmentReference-attachmentFeedbackLoopLayout-07311

If the attachmentFeedbackLoopLayout feature is not enabled, layout must not be VK_IMAGE_LAYOUT_ATTACHMENT_FEEDBACK_LOOP_OPTIMAL_EXT

VUID-VkAttachmentReference-dynamicRenderingLocalRead-09546

If the dynamicRenderingLocalRead feature is not enabled, layoutmust not be VK_IMAGE_LAYOUT_RENDERING_LOCAL_READ

Valid Usage (Implicit)

VUID-VkAttachmentReference-layout-parameter

layout must be a valid VkImageLayout value
