Not a problem--I'm happy to help

For this illustration I'm making a rigged catsuit for Sydney G2 with the QuickSuit (available from www.morphography.uk.vu). I open the QuickSuit file in Poser and go into the Setup Room. After I've loaded Sydney's bone structure and used the auto-grouping function, I get this:

The highlighted section is the collar group. See how the shoulder and chest group are touching (circled in red)? This arrangement will make the sleeve "tear" away from the bodice when the arm is moved. To fix it, I need to arrange the groups so that the collar comes between the chest and shoulder. I open the Grouping tool, select the collar group, and select the add polygons tool (plus sign icon):

When I click on a polygon with the add polygons tool, the polygon will be removed from whatever group it was in and added to the currently selected group (the collar in this case). There is also a remove polygons tool, which removes whatever polygons you clicked on from the selected group. I don't like to use it, though, because it doesn't add the polygons to a different group and I find it hard to remember all the polygons I removed. Usually when I mess around with the remove tool I end up forgetting to add the removed polygons to a different group, and polygons with no group cause problems. It's best to just add polygons to the group you want them to be in, rather than removing them from the groups you don't want them in.

You want to make the groups in the clothing polygons shaped as much like the groups in the base figure as possible. For this project, the collar group ends up looking like this:

Does that help? Just let me know if you need more clarification!

Also, if you're planning to make a lot of clothes you might want to invest in a Poser plugin such as the OBJ2CR2 from www.philc.net. It does all the dirty work of making conforming clothes, and I recommend it to anyone who's doing lots of conforming clothing. While it is completely possible to do conforming clothes by hand with the process I just described (it's how I made all of my first clothing items), the plugin speeds up the process greatly.
