VkRenderingAttachmentLocationInfoKHR

The VkRenderingAttachmentLocationInfoKHR structure is defined as:

typedef struct VkRenderingAttachmentLocationInfoKHR {
    VkStructureType sType;
    const void* pNext;
    uint32_t colorAttachmentCount;
    const uint32_t* pColorAttachmentLocations;
} VkRenderingAttachmentLocationInfoKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• colorAttachmentCount is the number of elements in pColorAttachmentLocations.
• pColorAttachmentLocations is a pointer to an array of colorAttachmentCount uint32_t values defining remapped locations for color attachments.

This structure allows applications to remap the locations of color attachments to different fragment shader output locations.

Each element of pColorAttachmentLocations set to VK_ATTACHMENT_UNUSED will be inaccessible to this pipeline as a color attachment; no location will map to it. Each element of pColorAttachmentLocations set to any other value will map the specified location value to the color attachment specified in the render pass at the corresponding index in the pColorAttachmentLocations array. Any writes to a fragment output location that is not mapped to an attachment must be discarded.

If pColorAttachmentLocations is NULL, it is equivalent to setting each element to its index within the array.

This structure can be included in the pNext chain of a VkGraphicsPipelineCreateInfo structure to set this state for a pipeline. If this structure is not included in the pNext chain of VkGraphicsPipelineCreateInfo, it is equivalent to specifying this structure with the following properties:

• colorAttachmentCount set to VkPipelineRenderingCreateInfo::colorAttachmentCount.
• pColorAttachmentLocations set to NULL.

This structure can be included in the pNext chain of a VkCommandBufferInheritanceInfo structure to specify inherited state from the primary command buffer. If VkCommandBufferInheritanceInfo::renderPass is not VK_NULL_HANDLE, or VK_COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT is not specified in VkCommandBufferBeginInfo::flags, members of this structure are ignored. If this structure is not included in the pNext chain of VkCommandBufferInheritanceInfo, it is equivalent to specifying this structure with the following properties:

• colorAttachmentCount set to VkCommandBufferInheritanceRenderingInfo::colorAttachmentCount.
• pColorAttachmentLocations set to NULL.
