Function Prototype

vkCmdSetColorBlendEnableEXT

Specify the pname:blendEnable for each attachment dynamically for a command buffer
primary / secondary
both
graphics
state

To dynamically set blendEnable, call:

void vkCmdSetColorBlendEnableEXT(
    VkCommandBuffer commandBuffer,
    uint32_t firstAttachment,
    uint32_t attachmentCount,
    const VkBool32* pColorBlendEnables);
  • commandBuffer is the command buffer into which the command will be recorded.
  • firstAttachment the first color attachment the color blending enable applies.
  • attachmentCount the number of color blending enables in the pColorBlendEnables array.
  • pColorBlendEnables an array of booleans to indicate whether color blending is enabled for the corresponding attachment.

This command sets the color blending enable of the specified color attachments for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_COLOR_BLEND_ENABLE_EXT set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineColorBlendAttachmentState::blendEnable values used to create the currently active pipeline.

Valid Usage
