It has no obj chain group because it is a conforming figure. As with most conforming hair, it follows most of the body's movements. Making it anything else, might give you more versatality in movement, but that would also mean that you wouldn't be able to stop it from cutting through the body at some other poses. This hair is created for ease of use; your model poses and your hair poses with it. I have experimented with obj linking in this model, but found the hair to be too time consuming for the users to pose and in many poses it looked far too unatural. That's why I decided to go with the conforming version. Thanks for the suggestions and for purchasing the product.
