# vkCmdSetColorBlendAdvancedEXT(3) Manual Page

## Name

vkCmdSetColorBlendAdvancedEXT - Specify the advanced color blend state dynamically for a command buffer

Loading… please wait.

## C Specification

To dynamically set the advanced blend state, call:

    // Provided by VK_EXT_blend_operation_advanced with VK_EXT_extended_dynamic_state3, VK_EXT_blend_operation_advanced with VK_EXT_shader_object
    void vkCmdSetColorBlendAdvancedEXT(
        VkCommandBuffer                             commandBuffer,
        uint32_t                                    firstAttachment,
        uint32_t                                    attachmentCount,
        const VkColorBlendAdvancedEXT*              pColorBlendAdvanced);

## Parameters

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

- `firstAttachment` the first color attachment the advanced blend parameters apply to.

- `attachmentCount` the number of VkColorBlendAdvancedEXT elements in the `pColorBlendAdvanced` array.

- `pColorBlendAdvanced` an array of VkColorBlendAdvancedEXT structs that specify the advanced color blend parameters for the corresponding attachments.

## Description

This command sets the advanced blend operation parameters of the specified attachments for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_COLOR_BLEND_ADVANCED_EXT set in VkPipelineDynamicStateCreateInfo::`pDynamicStates`. Otherwise, this state is specified by the VkPipelineColorBlendAdvancedStateCreateInfoEXT::`srcPremultiplied`, VkPipelineColorBlendAdvancedStateCreateInfoEXT::`dstPremultiplied`, and VkPipelineColorBlendAdvancedStateCreateInfoEXT::`blendOverlap` values used to create the currently active pipeline.

Valid Usage

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

  - The `extendedDynamicState3ColorBlendAdvanced` feature is enabled

  - The `shaderObject` feature is enabled

Valid Usage (Implicit)

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

- VUID-vkCmdSetColorBlendAdvancedEXT-pColorBlendAdvanced-parameter
  `pColorBlendAdvanced` must be a valid pointer to an array of `attachmentCount` valid VkColorBlendAdvancedEXT structures

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

- VUID-vkCmdSetColorBlendAdvancedEXT-commandBuffer-cmdpool
  The `VkCommandPool` that `commandBuffer` was allocated from must support VK_QUEUE_GRAPHICS_BIT operations

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

- VUID-vkCmdSetColorBlendAdvancedEXT-attachmentCount-arraylength
  `attachmentCount` must be greater than `0`

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 | VK_QUEUE_GRAPHICS_BIT | State

Conditional Rendering

vkCmdSetColorBlendAdvancedEXT is not affected by conditional rendering
