Subject: Why when I group do I get different pieces?

Ok I have been trying to model boxers for apollo.  Learning the process as I go.

I learned about grouping and have tried TWO different ways of doing it.  Using auto grouper program available here at rendo and also grouping right within poser.  Each time when I do it all the group seams seperate from eachother and I wind up with a clothing piece with gaps all over.

I know it can be done without the gaps or groups breaking up because a friend here did it once for me.  I really need to understand what part of this process I am missing.

You can see in this render if you look close at the sides of the crotch the mesh is split.  Its also split at every other group edge though the render doesn't show it.

Hi. Well, while not quite the right place for this particular question, I do think I have the answer:

The problem is most likely in how many polys you assign to a group vs. how many polys are in the mode itself.  

So, if we can see a wire of that same model, I'd hazzard that you didn't allow many polys in one area or the other.

If this turns out to not be the problem, than the answer is more likely the joint zones. That's simple enough and complex at the same time. Just make the joint zones visible and then adjust the red lines so that they don't extend beyond the boundary of group they're for.  If you try both things and still have trouble, post here and I'll move your thread to the Poser forum for ya.

I'm not sure that it is a poser related question.  SInce when my friend fixed this problem before she fixed it in a modeling program.  I simply rendered in poser to show you, that is the extent of posers relevance here.

When I grouped this time I used auto grouper to do it.

Apparently after 16 hours of frustration and beating Kirby for the 64 things can become more clear.  The answer to my problem appears to be:

You seem to have it sorted out, which is good. There's often some well hidden trick involved when trying to group in a Poser friendly manner in one's modelling app. Eventually you find a way that works for you and stick to it, mainly in terror of what might happen if you were to stray from the path. :) My well trodden path involves markdc's Auto Group Editor, and/or UVMapper. I never group within Poser, I've heard too many users griping about it...

Just wanted to say thank you for posting this. I am modeling a miniskirt for Jesse. It is the first time I have tried to model clothing. This would be my next step.

Eh well I had thought I had it figured out, what I posted here is one part though.  I'm still having some serious frustrations regarding the grouping but I now at least understand how Apollo clothing hip grouping HAS to be.  I didn't before.  Have to start over again today.

The problem is Poser. Poser can't handle a parent child relationship with more than one group. Your thigh groups are trying to weld to both the hip AND the genitals as parents. The fix is to create a small rim of polygons around the genitals that are actually part of the hip group, so that the thighs are only trying to attach to the hip, and the genitals are only trying to attach the hip. I learned about this limitation the hard way after I modeled my Reign of Fire Dragon and couldn't figure out how to bone him. IoDWingsWhite.jpg On that version the wing stops at the abdomen, on the original it went mostly all the way down the tail. I wanted a seperate chest, abdomen, and hip group for articulation, and wings that went all the way down the body. Never did figure it out.

Wow I wish I had learned about this on a model that cool : p

Thank you for the reply!

"Wow I wish I had learned about this on a model that cool" : p Thank for the compliment... and NO you don't! I must have killed a whole tree trying to figure out a Poser acceptible rigging solution before I gave up an back burnered it. My last attempt was trying to make the wings a seperate figure. Still didn't work. Poser is cool... and things like it's displacment mapping are actually better than a lot of other solutions out there, but it's skeleton system is really rather primitive compared with others these days.
