C Specification

To dynamically set the coverageReductionMode state, call:

// Provided by VK_EXT_extended_dynamic_state3 with VK_NV_coverage_reduction_mode, VK_EXT_shader_object with VK_NV_coverage_reduction_mode
void vkCmdSetCoverageReductionModeNV(
    VkCommandBuffer                             commandBuffer,
    VkCoverageReductionModeNV                   coverageReductionMode);


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

  • coverageReductionMode specifies the coverageReductionMode state.


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

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

  • VUID-vkCmdSetCoverageReductionModeNV-coverageReductionMode-parameter
    coverageReductionMode must be a valid VkCoverageReductionModeNV value

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

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

  • VUID-vkCmdSetCoverageReductionModeNV-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
