[WIP][SubD Topology][Maya] Best way to close rounded bottle/test-tube end?

mpedd · Sep 7 2025

Hi! I’m new to modeling and practicing SubD in Maya. I’m working on a bottle-like piece and I’ve reached the rounded end (think test-tube bottom). I’m not sure what the best way is to close this shape under smooth. Because it’s SubD I assumed it should be all quads instead of collapsing to the center, but when I fill it with quads I still get a faint circular dent at the very tip; if I collapse to the center I get a pinwheel/“flower” artifact. I also noticed that the bigger the center area of the quad cap is, the more visible the dent looks; pushing the quad fill all the way to the last ring (so the center is tiny) makes the dent much smaller. It doesn’t bother me as much now, but I’d love feedback to learn the proper approach. What do you usually do for this kind of curved cylinder end? triangle fan to the center, or a simple quad cap? If quad cap, any easy layout/tip to keep the highlight perfectly even would be super helpful. Is there a reliable way to cap this so it shades perfectly smooth in SubD, or is that tiny dent normal and people just live with it? I attached unsmoothed and smoothed wires plus a shaded view. Thanks!
