I am following an online tutorial by Blender Guru. I added in a new object (encircled in red below), which I originally applied smooth shading to
However, when I made this part of the overall mesh using CTRL + J, the smooth shading disappeared. How do I make this particular part circled in red smooth shading, without affecting the rest of my mesh?
EDIT: Thank you I've done that, it's smoothed it a little however you can still see the lines, see below. Is there anyway to make it even smoother?
