# vkCmdSetCoverageModulationModeNV(3) Manual Page

## Name

vkCmdSetCoverageModulationModeNV - Specify the coverage modulation mode dynamically for a command buffer

Loading… please wait.

## C Specification

To dynamically set the `coverageModulationMode` state, call:

    // Provided by VK_EXT_extended_dynamic_state3 with VK_NV_framebuffer_mixed_samples, VK_EXT_shader_object with VK_NV_framebuffer_mixed_samples
    void vkCmdSetCoverageModulationModeNV(
        VkCommandBuffer                             commandBuffer,
        VkCoverageModulationModeNV                  coverageModulationMode);

## Parameters

- `commandBuffer` is the command buffer into which the command will be recorded.

- `coverageModulationMode` specifies the `coverageModulationMode` state.

## Description

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

Valid Usage

- VUID-vkCmdSetCoverageModulationModeNV-None-09423
  At least one of the following must be true:

  - The `extendedDynamicState3CoverageModulationMode` feature is enabled

  - The `shaderObject` feature is enabled

Valid Usage (Implicit)

- VUID-vkCmdSetCoverageModulationModeNV-commandBuffer-parameter
  `commandBuffer` must be a valid VkCommandBuffer handle

- VUID-vkCmdSetCoverageModulationModeNV-coverageModulationMode-parameter
  `coverageModulationMode` must be a valid VkCoverageModulationModeNV value

- VUID-vkCmdSetCoverageModulationModeNV-commandBuffer-recording
  `commandBuffer` must be in the recording state

- VUID-vkCmdSetCoverageModulationModeNV-commandBuffer-cmdpool
  The `VkCommandPool` that `commandBuffer` was allocated from must support graphics operations

- VUID-vkCmdSetCoverageModulationModeNV-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

Command Properties

Command Buffer Levels | Render Pass Scope | Video Coding Scope | Supported Queue Types | Command Type
--- | --- | --- | --- | ---
Primary Secondary | Both | Outside | Graphics | State
