so, i have read many times by gmask that global stitch is mainly meant for keeping patches together for animation. now, i have just about finished my face except for the fact that there are creases inbetween patches as they have not been stitched at all.
i was reading a tutorial for patch modelling a head, and once the modelling was done, he went straight to the global stitch, and used stitch edge primarily when global did not produce the desired results. and in this senario global stich worked really well for eliminating the seems.
so my question is: by jumping right into global stitch without stiching edges first, am i missing any valuable steps.
if someone could briefly explain what the difference between these two are in the sense of what these functions actually produce that would be great. thanks for your help.
..OK I have said that using the global stitch is only best for keeping patches together during aniamtion but it is a useful modelling tool buyt can only correct minor problems. If the surfaces aren't allreayed very close and also built correctly is will only make more of a mess of pre-existing problems.
Global stitch is a tool that attempts to align all adjacent edges smoothly. Regular stitch requires you to pick pairs of edges and stitch. So global stitch is more automatic, but regular stitch gives you more control for problem cases.
One workflow would be to try global stitch first then, if you see problems, undo and do regular stitch or align on the problem edges, then delete history and redo global stitch.
As you say, global stitch is really a tool to maintain smoothness under animation rather than create it from unaligned intitial surfaces, so the closer you can get your patches to line up before using global stitch, the better.
Two methods I have used to get those patches really close before global stitch are these. Select the corner CV's of the adjoining patches and then use the stitch surface points. You can also select those same CV's and use the scale tool to scale them closer and then use global stitch.
