vkCmdSetRenderingInputAttachmentIndicesKHR

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

void vkCmdSetRenderingInputAttachmentIndicesKHR(
    VkCommandBuffer commandBuffer,
    const VkRenderingInputAttachmentIndexInfoKHR* pInputAttachmentIndexInfo);

commandBuffer is the command buffer into which the command will be recorded.
pInputAttachmentIndexInfo is a VkRenderingInputAttachmentIndexInfoKHR 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 currently bound pipeline, if one is bound, which can be set by chaining VkRenderingInputAttachmentIndexInfoKHR 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
