vkCmdSetColorBlendAdvancedEXT

Specify the advanced color blend state dynamically for a command buffer

state

To dynamically set the advanced blend state, call:

void vkCmdSetColorBlendAdvancedEXT(
    VkCommandBuffer commandBuffer,
    uint32_t firstAttachment,
    uint32_t attachmentCount,
    const VkColorBlendAdvancedEXT* pColorBlendAdvanced);
  • 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.

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.
