i found the shaderball's edge bevel is nice,but when i tried with polybevel ,there are artifacts, don't know is it possible to fix it?

and i tried with nurbs round,i don't konw how to delete the rest corner! ops:

Three important things to remember when using the polybevelSOP: the points have to be shared, the points have to be common, and the normals have to be correct. That is to say, each meeting surface should have the same points in the same place and that the normals should be facing in the correct direction.
