Otherwise, to dynamically set and change the blend constant, call:

void vkCmdSetBlendConstants(
    VkCommandBuffer                             commandBuffer,
    const float                                 blendConstants[4]);


  • commandBuffer is the command buffer into which the command will be recorded.

  • blendConstants is a pointer to an array of four values specifying the R, G, B, and A components of the blend constant color used in blending, depending on the blend factor.

  • commandBuffer must be in the recording state

  • The VkCommandPool that commandBuffer was allocated from must support graphics operations
