Try using a FWN script and apply it before you bake. Otherwise, remove the chamfers and give each cylinder a separate smoothing group (with a separate UV)
Thanks for the replies @Kanni3d, yes, I use the FWN script. I'm only allowed to use one smoothing group, so the chamfer is necessary for when I use weighted normals. @Ghogiel, yes, normal thief helped in the end. Smoothing group issue was due to an oversight on my part. FWN alone caused some problems - it resolved some…
