vkCmdSetColorBlendEnableEXT
To dynamically set blendEnable, call:
void vkCmdSetColorBlendEnableEXT(
VkCommandBuffer commandBuffer,
uint32_t firstAttachment,
uint32_t attachmentCount,
const VkBool32* pColorBlendEnables);
commandBufferis the command buffer into which the command will be recorded.firstAttachmentthe first color attachment the color blending enable applies.attachmentCountthe number of color blending enables in thepColorBlendEnablesarray.pColorBlendEnablesan 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.
