View Full Version : Subdivision Surface Help

I'm currently in the process of teaching myself modeling with subdivision surfaces, but I have recently found some problems. Whenever I edit subdivision components, it doesnt affect the polygon cage--which I expected--but, after I edit the components, and then if I edit the polygon cage, it wont let me edit any more of the components. If anyone can answer any of the following questions I'd appreciate it: Is there any way I can overcome this? Is it better to model completely with the polygon cage? Is there any way I can make the polygon cage fit the subdivision surface after its components have been edited?

Also, another, rather unrelated question about subdivisions regards selecting edges (perhaps other components too). Whenever I select subdivision edges, in standard mode, I cant see selected edges at some angles. Is this supposed to happen? Is there any way I can see selected edges at all angles?

Thanks in advance.

Can you be more specific as to what it is that your modeling and why you are facing the issues?

I have found subDs to be excellent... however, I do come from a primarily Nurbs based background... meaning that when I originally started to learn 3D, I did only Nurbs for about a year... and I think that that gave me a better perspective for subDs.

I tend to rough out the design as a poly and try to keep the shape efficient, meaning that if I was going to do a sphere type model I would not go beyond a poly cube... so you end up with a subD sphere that has level 0 verticies that are a cube. Overtime I have found that once I convert my poly into a subD, that I rarely go back into poly mode when refining the detail.

So the poly cage represents the standard mode's level zero verticies... so if you edit the level zeros it should affect the poly cage... but anything deeper than that will not affect the poly cage..... is that not happening for you????
