void vkCmdSetBlendConstants( VkCommandBuffer commandBuffer, const float blendConstants[4]);This command sets blend constants for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_BLEND_CONSTANTS set in VkPipelineDynamicStateCreateInfo ::pDynamicStates. Otherwise, this state is specified by the VkPipelineColorBlendStateCreateInfo ::blendConstants values used to create the currently active pipeline.
