How to Make Smooth Bevel Curve Without Extra Crease? I want to make something like a curve-shape pipe,
so I use curve (I make an edge and convert it to curve because I need it like that in original work) and bevel it with bevel&gt;object&gt; beziercircle and it looks like that:

After that I convert it to mesh, and do bevel of the angle edge loop in the middle

But it look like that:

So how can I make it even and smooth without these crease that indicated by red arrows?
I add subdivision modifier and auto-smooth but it still the same.
Maybe put an additional edge loop close to it, it should attenuate the problem:

If you ever want an alternative that works (but the whole profile is different so it may not be what you want):
Create your pipe with a series of vertices, when you want to curve an angle, bevel the vertex:


Convert to curve, go in the Properties panel &gt; Object Data &gt; Geometry, and bevel:
