vkCmdSetColorBlendEnableEXT(3)

C Specification

To dynamically set blendEnable, call:

// Provided by VK_EXT_extended_dynamic_state3, VK_EXT_shader_object
void vkCmdSetColorBlendEnableEXT(
    VkCommandBuffer                             commandBuffer,
    uint32_t                                    firstAttachment,
    uint32_t                                    attachmentCount,
    const VkBool32*                             pColorBlendEnables);

Parameters

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.

Description

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

At least one of the following must be true:
- The extendedDynamicState3ColorBlendEnable feature is enabled
- The shaderObject feature is enabled

Valid Usage (Implicit)

commandBuffer must be a valid VkCommandBuffer handle
VUID-vkCmdSetColorBlendEnableEXT-pColorBlendEnables-parameter
pColorBlendEnables must be a valid pointer to an array of attachmentCount VkBool32 values
VUID-vkCmdSetColorBlendEnableEXT-commandBuffer-recording
commandBuffer must be in the recording state
VUID-vkCmdSetColorBlendEnableEXT-commandBuffer-cmdpool
The VkCommandPool that commandBuffer was allocated from must support graphics operations
VUID-vkCmdSetColorBlendEnableEXT-videocoding
This command must only be called outside of a video coding scope
VUID-vkCmdSetColorBlendEnableEXT-attachmentCount-arraylength
attachmentCount must be greater than 0

Host Synchronization
