C Specification

The VkPipelineColorWriteCreateInfoEXT structure is defined as:

// Provided by VK_EXT_color_write_enable
typedef struct VkPipelineColorWriteCreateInfoEXT {
    VkStructureType    sType;
    const void*        pNext;
    uint32_t           attachmentCount;
    const VkBool32*    pColorWriteEnables;
} VkPipelineColorWriteCreateInfoEXT;


  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • attachmentCount is the number of VkBool32 elements in pColorWriteEnables.

  • pColorWriteEnables is a pointer to an array of per target attachment boolean values specifying whether color writes are enabled for the given attachment.


When this structure is included in the pNext chain of VkPipelineColorBlendStateCreateInfo, it defines per-attachment color write state. If this structure is not included in the pNext chain, it is equivalent to specifying this structure with attachmentCount equal to the attachmentCount member of VkPipelineColorBlendStateCreateInfo, and pColorWriteEnables pointing to an array of as many VK_TRUE values.

If the colorWriteEnable feature is not enabled on the device, all VkBool32 elements in the pColorWriteEnables array must be VK_TRUE.

Color Write Enable interacts with the Color Write Mask as follows:

  • If colorWriteEnable is VK_TRUE, writes to the attachment are determined by the colorWriteMask.

  • If colorWriteEnable is VK_FALSE, the colorWriteMask is ignored and writes to all components of the attachment are disabled. This is equivalent to specifying a colorWriteMask of 0.

Valid Usage
  • VUID-VkPipelineColorWriteCreateInfoEXT-pAttachments-04801
    If the colorWriteEnable feature is not enabled, all elements of pColorWriteEnables must be VK_TRUE

  • VUID-VkPipelineColorWriteCreateInfoEXT-attachmentCount-07608
    attachmentCount must be equal to the attachmentCount member of the VkPipelineColorBlendStateCreateInfo structure specified during pipeline creation

  • VUID-VkPipelineColorWriteCreateInfoEXT-attachmentCount-06655
    attachmentCount must be less than or equal to the maxColorAttachments member of VkPhysicalDeviceLimits

Valid Usage (Implicit)
  • VUID-VkPipelineColorWriteCreateInfoEXT-sType-sType

  • VUID-VkPipelineColorWriteCreateInfoEXT-pColorWriteEnables-parameter
    If attachmentCount is not 0, pColorWriteEnables must be a valid pointer to an array of attachmentCount VkBool32 values
