SubD Spaghetti Junction
 

hi guys,

Im new to maya and am picking it up quickly (thanks to simplymaya.. awesome site ;) ) but i have a problem that is really bugging me. I create a nurb head, convert to polygons. Then i split some polygons... when i convert to subDs the edges in certain areas go like spaghetti. no longer straight but all randomly wonky. can any help me?!?!?!

any help would be greatly appreciated

thanks

Maybe delete the history.

Edit>Delete By Type>History.

you could have some extra geo there you don't know about also. A screen shot of the problem could helpl.

Two options come to my mind immediately;
[list=1]1_You have a normal subD conversion that filters the topology display in order to catch the curvature.

2_You have some orphaned vertices (Vertices that remain after you delete an edge intersecting another one) And it is taking it in account.[/list=1]

If you haven't come cross it earlier a SubD can seem to do funny things to the wireframe via conversions. Sort of looking more like an Aztec work of art rather than a wireframe. If it is something like this don't worry about it. Just clean the model a bit better the next time before you convert it if you don't like the looks of things. Like watch to make sure the faces are planer and not n-sided (more than 4 sides) But if it isn't bothering you and it is a seriously complex structure all together.. leave it. Won't really ruin anything.

As for if you have extra vertices that have no serious use; Just select the whole object and press delete. MaYA only removes orphaned ones as they have no dependency layed on them.
Important note!! Orphaned means a vertice on an edge with no other connections. This means a total of maximum 2 connections. A vertice on the corner of a plane (Not a cube) ALSO has 2 connections only. So if you have an open mesh constructed of planes; then you may want to unselect the ones in the corners.

Shall it be that your problem is neither of the above; you have to post a sample picture for us to be able to help you on it. Or at least myself. I can't think of another reason that fits the discription.

maybe you need link these neighbor point ,try to do it.

I'm sorry, I have to do an aside here... Spaghetti Junction? Matt do you live in around or near Atlanta? Those are my old stomping grounds. I moved to Sioux falls, SD three years ago but still miss my Southern home. :)
