C Specification

To dynamically set the stencil compare mask, call:

// Provided by VK_VERSION_1_0
void vkCmdSetStencilCompareMask(
    VkCommandBuffer                             commandBuffer,
    VkStencilFaceFlags                          faceMask,
    uint32_t                                    compareMask);


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

  • faceMask is a bitmask of VkStencilFaceFlagBits specifying the set of stencil state for which to update the compare mask.

  • compareMask is the new value to use as the stencil compare mask.


This command sets the stencil compare mask for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_STENCIL_COMPARE_MASK set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkStencilOpState::compareMask value used to create the currently active pipeline, for both front and back faces.

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

  • VUID-vkCmdSetStencilCompareMask-faceMask-parameter
    faceMask must be a valid combination of VkStencilFaceFlagBits values

  • VUID-vkCmdSetStencilCompareMask-faceMask-requiredbitmask
    faceMask must not be 0

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

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

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

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