Request to improve hair product with ERC ghost bone (Top model hair etc)

Hi as same as many users I really like out of touch hair product . then I got Top model hair in sale. Out of touch hair mats is very good, and It has many morph with individual ghost bone for hair to pose easy.
then I really like this hair style with many variation.
Today I use this hair for my characetr, which adjust body size by height morph (it is default shape morph, which change character height)
I try to pose hair by bone rotation (tail bones) and I found it deform somehow strange way. then I check current joint, and found
those ghost bone seems have no ERC with generated height morph. (FBMheight)
I know, it is difficult to apply ERC about all hair ghost bone for all shape morphs, but I really hope to set ERC about height morph.
because Height morph (FBMheight) is basic morph to adjust character height. We use it many times. do not you?
But if ghost bones have no ERC to adjust nodes position, hair pose with ghost bone rotate, not work well. (pivot point do not work correctly)
I do not hope perfect auto adjust hair with ghost bone,, but if vendor plan to offer hair with ghost bone,, I expect there should be some ERC for basic morphs. or make erc for head joint postion, then auto adjust ghost bone positon to head node postion. (maybe it is more useful to work with many morph)
This is request for vendors who plan to offer hair with ghost bone.( I really like the way)

I'm not sure it's something that is easily fixed without creating a custom hair rig. I will see what I can figure out here.
Just have to adjust rigging to shape for that morph.. not really a big deal.
you might try parenting the hair to the character instead of fitting it to it, just to test it and see if that works. trying it this way the hair morphs are as they were when they were created. and the hair is just sitting on the head of the character instead of applying all the bones to the shoulders and neck etc. like it does when you fit it. I parent genesis3 hair & props on all other generation of characters and this trick works great, so as a work around I would try parenting it instead of fitting too. when you parent a hair item it will auto follow the scale of your character so if you reduce the scale of the character the hair should scale as well but parent the hair prop before you start your re-scaling of your character.

yes actually those product with custom rig which can pose easy as bone and weight for hair part. but this problem should happen, about all product which have ghost bone, those follower ghost bones which have not in Actor rig, can not follow morphed shape position by Actor morph which change rig position.
then vendor may plan to make ERC for generated moprh then save it as original morph for hair, to adjust shape.But make all ERC for all daz offered morph is almost impossible, but I hope, if they can add ERC morphs for some base morphs like Height. or Now I am thinking more better ERC to circuloate correct rig postiion, by hair head bone. then set ERC (though it seems difficult about curernt daz offered parameter,,when fit to,,)

Usually adjust rigging to the shape work good I know well, but it depend on much how hair rig and new added bones are assigned to mesh group for weight mapped. This OutofTouch hair is not simple rig. it offer controll bone with parented (there is no weight map), if you try it about same product, you may find , it is not easy ,even though you try to adjust rig one by one, for those control bone, with the option.
(to be frankly said, there is many case, adjst rigging to the shape not work well, about rigging which have many controll bone without weight map)
after all I needed to adjust rigs by may sefl aproximately, for current many mix morphed shape, included height. But adjust rigging to the shape is temp, it work only about current morph value. after all every time re-adjust rigging to the sahpe for each Actor and morph which controll rigs, if you feel it is not heavy problem , it is your opinion . but as customer, I do not like such way.
And I feel, about daz studio and daz figure,, follower ghost rig (include grafting items) can not follow base rig position when fit to,, is Priority issues to improve daz product more for long time. after daz offer genesis figures, (auto genearte morphs , and fit to,, etc)
if DAZ can offer way to auto adjust rigs correspond to generated morph, about fit to item., or vendor offer add on, which can auto set ghost rig positon correclty, I really apreciate.
>Ivy yes, actually I know parenting is one good alternate method. but as you know, it is optional way. because parenting can not auto set ingected morph values from Actor. then if I use many morph, this time I need manually adjust shape for hair, to fit to current shape.I may inject those moprhs once, then un-parent and set those values manually etc. but keep parented not fit to is practical good way I know.
