vkCmdSetRenderingInputAttachmentIndices

Set input attachment index mappings for a command buffer

To set the input attachment index mappings during dynamic rendering, call:

void vkCmdSetRenderingInputAttachmentIndicesKHR(
    VkCommandBuffer commandBuffer,
    const VkRenderingInputAttachmentIndexInfo* pInputAttachmentIndexInfo);
  • commandBuffer is the command buffer into which the command will be recorded.
  • pInputAttachmentIndexInfo is a VkRenderingInputAttachmentIndexInfo structure indicating the new mappings.

This command sets the input attachment index mappings for subsequent drawing commands, and must match the mappings provided to the bound pipeline, if one is bound, which can be set by chaining VkRenderingInputAttachmentIndexInfo to VkGraphicsPipelineCreateInfo.

Until this command is called, mappings in the command buffer state are treated as each color attachment specified in vkCmdBeginRendering mapping to subpass inputs with a InputAttachmentIndex equal to its index in VkRenderingInfo::pColorAttachments, and depth/stencil attachments mapping to input attachments without these decorations. This state is reset whenever vkCmdBeginRendering is called.

Valid Usage

VUID-vkCmdSetRenderingInputAttachmentIndices-dynamicRenderingLocalRead-09516

dynamicRenderingLocalReadmust be enabled

VUID-vkCmdSetRenderingInputAttachmentIndices-pInputAttachmentIndexInfo-09517

pInputAttachmentIndexInfo→colorAttachmentCount must be equal to the value of VkRenderingInfo::colorAttachmentCount used to begin the current render pass instance

VUID-vkCmdSetRenderingInputAttachmentIndices-commandBuffer-09518

The current render pass instance must have been started or resumed by vkCmdBeginRendering in this commandBuffer

Valid Usage (Implicit)

VUID-vkCmdSetRenderingInputAttachmentIndices-commandBuffer-parameter

commandBuffer must be a valid VkCommandBuffer handle

VUID-vkCmdSetRenderingInputAttachmentIndices-pInputAttachmentIndexInfo-parameter

pInputAttachmentIndexInfo must be a valid pointer to a valid VkRenderingInputAttachmentIndexInfo structure

VUID-vkCmdSetRenderingInputAttachmentIndices-commandBuffer-recording

commandBuffer must be in the recording state

VUID-vkCmdSetRenderingInputAttachmentIndices-commandBuffer-cmdpool

The VkCommandPool that commandBuffer was allocated from must support graphics operations

VUID-vkCmdSetRenderingInputAttachmentIndices-renderpass

This command must only be called inside of a render pass instance

VUID-vkCmdSetRenderingInputAttachmentIndices-videocoding

This command must only be called outside of a video coding scope

Host Synchronization

  • Host access to commandBuffer must be externally synchronized
