This is kinda hard considering the top fins are near the edges of the cylinder, beyond the support loop. I'm not sure how to tackle this. Adding an extra loop would just make the curvature more sharp ?
You don't want to disturb the edge flow or create 5 edge poles along a clean cylinder like that. Try to terminate any loops or edges on the flat surface away from the loop.
@perandall not sure what exactly your question is but I suppose you're talking about pinching artifacts caused by uneven spaced loops ? If so enable loop tools addon under blender preference > select the row of edges you wanna space like this > loop tools > space. You can also add an extra softness by using the relax…
Gotta be really careful when adding edge loops around a consistent smooth curve. Generally it's easiest to start with more geometry and you can terminate those extra edge loops in flat areas where it wont affect smoothing. I'd probably start with 36 or 72 loops around that cylinder.
Need some more loops on the lonely loop on the inside. I bet if you carried the loops on the topside around the front and to the underside it would create some nice edge flow and help smooth out the inside.
Hello, I have that kind of shape, and I do not know how to deal with it, how to add suport loop, especially in the marked place. there is so tight and no place for support loop. please help
That describes what Perna was saying, by adding the new loop and deleting the original, you've lost some of the cylindrical shape. By shifting part of one control loop into a structural loop of another, you're going to have a mismatch of form.
Try selecting the entire loop (navy) and giving it a chamfer (yellow). This will be a complete support loop for that edge to be tightened up, however, it's possible you'll get an unwanted pinch/tight effect on the other end of that loop. Right now you have some support loops that are terminating too soon, and also…
