C Specification

To dynamically set the sample mask, call:

// Provided by VK_EXT_extended_dynamic_state3, VK_EXT_shader_object
void vkCmdSetSampleMaskEXT(
    VkCommandBuffer                             commandBuffer,
    VkSampleCountFlagBits                       samples,
    const VkSampleMask*                         pSampleMask);


  • commandBuffer is the command buffer into which the command will be recorded.

  • samples specifies the number of sample bits in the pSampleMask.

  • pSampleMask is a pointer to an array of VkSampleMask values, where the array size is based on the samples parameter.


This command sets the sample mask for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_SAMPLE_MASK_EXT set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineMultisampleStateCreateInfo::pSampleMask value used to create the currently active pipeline.

Valid Usage
Valid Usage (Implicit)
  • VUID-vkCmdSetSampleMaskEXT-commandBuffer-parameter
    commandBuffer must be a valid VkCommandBuffer handle

  • VUID-vkCmdSetSampleMaskEXT-samples-parameter
    samples must be a valid VkSampleCountFlagBits value

  • VUID-vkCmdSetSampleMaskEXT-pSampleMask-parameter
    pSampleMask must be a valid pointer to an array of VkSampleMask values

  • VUID-vkCmdSetSampleMaskEXT-commandBuffer-recording
    commandBuffer must be in the recording state

  • VUID-vkCmdSetSampleMaskEXT-commandBuffer-cmdpool
    The VkCommandPool that commandBuffer was allocated from must support graphics operations

  • VUID-vkCmdSetSampleMaskEXT-videocoding
    This command must only be called outside of a video coding scope

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

  • Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
