WebJan 23, 2024 · To show the actual “color” of the channel, we first need to take apart the image using cv2.split. We need to reconstruct the image, but this time, having all pixels but the current channel as zero. On Line 31, we construct a NumPy array of zeros, with the same width and height as our original image. The mesh should not have any absolute deformations in the deformation chain. This includes blendShapes that still have the targets connected. See more
