| Thanks Magic Pen. Polycount is officially the slowest site on the internet, and Max Forums doesn't like my browser. But CG Channel looks good. I will try that one. |

So I decide to try this editable poly thing, since I'm getting pretty tired of animating patches.
I'm making a head model in low res, then turning on NURMS subdivision to make it all smooth. After about an hour everything is going great, until I add the nose. Then this happens:
The top pic is with subdivisions 1, the bottom with subdivisions 2. These spikes shoot out either into the left bottom corner of the viewport, or they fly out into infinity. Sometimes they show up in the render, sometimes they don't. But they do show up in all four viewports, even after a screen refresh. So it's really there, it's not some rendering anomaly.
I've tried deleting polys, rearranging them, etc. I can narrow it down to individual polys, because when I delete them the problem goes away. But when I rebuild them, even in a different configuration, the problem still appears as soon as I turn on NURMS subdivision. All of the offending polys have fours sides, they are in a nice shape, not weird at all.
I don't think it's a bug, I think it's my problem. But my attempts to fix it have just made it worse. I guess I need to know what causes this before I can fix it. I want to do it now before I spend a lot of time on a model.
Anyone know what causes this? |

Heh, OK. In every problem area I had small polys next to larger polys, at acute angles. The spikes happened when, because of the smoothing, vertices got blown out to great distances.
So, there wasn't really a problem per se. It was just a result of normal smoothing. Adjusting the "crease" and "weight" of edges fixed the problem. |
