Thank you for your advice, @Astrotronic and @jwatte . I tried changing the Shading mode of the master material to’ Unlit’, but the static mesh seems to have become hard to see, almost as if it disappeared from the viewport (yet, they are existing and I can barely see them black and white color based on the angle. This is not the appearance I was aiming for. I guess I made a mistake, could you please explain the correct method in more detail?
