Wrong grouping in Autogrup Editor after Hexagon - what is the matter?

wargis

Hello! Can someone propmt me what may be the matter with grouping problems after editing clothes in Hexagon 2.5? I start to learn modeling and tried to adjust a mesh of converted pants (from V3 to V4), and after closing all mesh gaps, rewelding and remapping it I put the pants into Autogroup Editor. In the window of AE all looks quite fine but after grouping all groups go wrong. The Hip zone spreads just to the middle line (though I tried this time to avoid cutting pants along this symmetry line) and eats parts of Thigh zones, all thighs follow this deformation, just shins look nearly normal. I guess the problem is in the Hip area but cannot find it. all i found was a pair of stray vertices on non-4-edges facets. I corrected this, but with no effect. Here are some screenshots to illustrate the problem.
The view in AE window -

And the result as it is in the outgoing grouped mesh (I turned off the visibility of affected groups, so you can see).

Along with V4's OBJ loaded (her hip is turned off to compare meshes) -

I see no visible serious defects in the mesh of pants - the one, which I got after convertation, remained almost intact. And I have not found even n-gons, which could be the possible source of this problem. In the original mesh hip zone takes its real place and made also in Autogroup Editor, just for V3. There was also Abdomen-grouped parts, but in the newly grouped for V4 mesh AE doesn't transfer this group (apparently these polygons don't overlap Vicky's abdomen).

So what may be wrong? Is there any serious difference between V3 and V4, so may cause such problems or the matter is in polygonal structure of the mesh or in the settings in Hex? I export OBJ with such settings -

Should I turn on something else in them or correct something else in Hexagon? I understand I made something wrong in the mesh but I don't know what namely.

The only thing I can think about right now is that if AE actually makes several split areas in, say, hip. When combined they all look right in AE but Hexagon, because it might perceive such groups differently, it might see some of those groups as 'hip' and some as something else, thus irregularity.

As for export, I'd try to uncheck 'Merge Equal Points' and see if it works.

Also, I can look into meshes for you: I'll send you a PM with my coordinates if you'd like for me to do this.

Hello, Kattey! Many thanks to you for responding! It seems my inbox here looks empty - maybe my browser misses JS or anything, so I write here. I've read your letter late because of my mailbox' spam settings, now people from other forum explained me the possible reason of my problems already - as I understood, Hexagon, even version can 2.5 change the order of vertices in meshes, that causes this wrong splitting in AE. They adviced me to use Wardrobe Wizard 2 instead of AE, which can "convert" a welded or altered mesh and group it for V4 (this is a false conversion from V4 to V4 but it works for me!) So I could get the new grouped well-conforming OBJ and CR2, and it solved my problem. (Simply I'm a beginner and never used WW2 for such false conversions). So I wouldn't bother you and take your time with my noob problems, which I have in learning 3D - it remains my little hobby yet. Thank you once more for smart advice about AE - I've just began to use it and did not go deep into this automatic grouping at all.

Not a problem, glad you had your situation resolved :D

As for Hexagon changing vertices order, I'm a bit surprised because while Hexagon _can_ change vertices order like any other modeller it doesn't do it for me on import/export (i.e. I export and import meshes from and into Hexagon from a number of modeling programs). I'd still check if 'Weld similar vertices' causes the problem.

As for 'noob' question - don't worry and ask if you need a help. Everybody here was a noob once ^_^"
