vkCmdSetColorBlendAdvancedEXT(3)

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.
