Way back when, I got myself into a heap of trouble by trying to parent clothing that was already conformed. I don't recall now if I'd selected "inherit bends of the parent," but everything kept getting so messed up that I finally stopped using that method to "organize" clothing in the Hierarchy Editor. What I do now is give the figure a short name in ALL CAPS and put that figure's name, also in ALL CAPS, at the start of each of their clothing item names. So, for example, if I have V4 LAUREN, I may also have LAUREN Skirt, LAUREN Blouse, and so on. That makes it easy to spot which items go with which figure when I have more than one in a scene.
I've also gotten myself into a heap of trouble parenting lights to Grouping Objects (along with a bunch of props) and then scaling the Grouping Object. Somewhere along the way, I must've un-parented and re-parented the lights, because somehow I ended up with point and area lights that were so badly distorted I had to just start over!
So now I'm a lot more careful with how I set up Grouping Object groups, based on how I intend to use the group (for mass transformations, for easy on/off visibility, for Hierarchy Editor neatness, etc.). When I put figures into a Grouping Object so I can more easily move them collectively, I don't put their conformed clothing into the Grouping Object, as that also created some funky problems way back when (I guess b/c the clothing was being told to translate or rotate both by the Grouping Object and by the figure it was conformed to).
Apparently the way I've learned to use Poser is by getting myself into, and then out of, all kinds of trouble ;-)
Ken, re: a quick way to move parameter dials into a group: it would sure help if parameter dials could be shift-selected like most things in a list-type interface (to select all the items between the first and last selection, rather than just adding on selection at a time). It drives me batty when I've selected 14+ parameter dials and accidentally release the shift key when selecting the 15th, thus losing my entire selection!
Another fix that would help with SO MANY things is if all lists in Poser were collapsed by default, rather than open by default. If I added up all the time I've ever spent collapsing lists just so I can see what my options were, I'm sure it would amount to over a day or two
