Attach clothes, hair, props to 3d model

da_ateam

Hi I'm new here, but here is my question.  I've created a 3d model and applied warbrobe and props.  Next I use the new Unity  Bridge to export everything over to Unity 2019.4xx.  I've evn managed to add an animation through the Unity Mecanim system.  Problem is the clothing and hair and props are not attached.  They do not animate with the 3d model.  This was the same problem that made me stop using Daz a couple of years ago. There doesn't seem to be an option to combine the meshes.  How do I attach or make the accessories? Or make them children of the model? or What ever is it that I have to do?
