Hi I am planing to send bug report about one product bottom underwear for genesis3female, but at same time, I hope to know the reason why it happen.
https://www.daz3d.com/ikaros-outfit-for-genesis-3-female-s
I do not know celar,, if vendor can remove this problem or not, then If I understand the reason, I may hope to correct it by myself, then wait vendor up-date (or not). And I can avoid this problem , when I make thse under wear too. So that I hope to ask ds users, if you can find reason why it not work,, (and if you have same product, prease test it,, )
I happend to change my character clothing panty to ikaros panty.
then found it not fit at all for my character, I afraid, if it is saved scene problem, but not. I load default genesis3F another scene, then load this panty, and test much.then I found some morph not auto-follow at all to this underwear
1. load genesis3female , then select it and load ikaros panty. (fit to) now the shape fit to genesis3female. there seems no problem.
2 apply body morphs which can change west or hip size for G3F, but this panty not auto-follow well about many (but not a few) morphs which change west size 
I see this problem clear, Actor/fullbody/thin, or, Actor/fullbody/Body Size,, or Heavy or Thin,, I just set 20% or 10 % it actually start show gap clear enough. you can see those pic,, I seldom see such product panty, which can not auto follow well about those baseic morph,,. (I often see problem when I pose,, but this problem is not pose,, )
Of course, same problem should happen, when I apply morphs of daz charcter correction,, there are too many caharcter who can not wear this panty
I may no need to show all character with this panty,,
(to be frankly said, I can not use this product panty with morphed character.. but it seems only work about some character morphs. (maybe vendor overwrite those by morphs) I know we can often rely smooth modifier, but too large gap not help it.
3 The interesting thing is,, I chack other bottom wear which looks a like, but most of them can auto follow without problem about those morphs.
(though sometimes vendor offer original morphs, to overwrite, but other pants can follow well (I think auto-follow only). last pic show, I rondom apply morphs, then compare with other my panty,, correction,,,><;),,,,,, then my question is, why only this panly can not follow morphs well, what is special?
I check weight map, or joint etc,, and parameter setting of this product,,, but I can not find clear reason if I transfer weight again it can auto-follow well?
And this panty actuall "fit to" character, so do not ask me,, it seems not fit to,,, and I can show those genearte morph, as hidden morphs about this panty too.
