How G8F morphs automatically work on her dress?

I created a dress in Hexagon and imported it back to Daz Studio as OBJ file. Then I used "Transfer Utility" to auto-rig it. 

Now when I apply ANY morph to G8F a dress also follows that morph. If I go to "Parameters" tab of a dress and activate "Show hidden properties" I can see that all applied to G8F morphs are also here.

Does Daz Studio copies all active morphs from G8F to Dress figure? How it knows which vertices of the dress to morph when base morph is applied on G8F? 

I looked inside .DUF and .DSF files of a dress and there were NO mentions of any of applied morphs. That means Daz Studio somehow intellectually knows how to morph a dress, but does it do it?

I don’t know how it does that technically but yes, DS includes a feature called “auto follow” which will automatically project morphs (tagged with “auto follow” in morph properties) from the figure to the clothes.

I am working on 3D game where clothes need to be morphed also when G8F body morphs that is why I need to understand how to implement it )

I know that each morph (.DSF file) of Genesis 8 Female contains an array named "deltas" with indexes of vertices that need to be changed and X,Y,Z values.

I am curious, does Daz Studio uses these G8F morph indexes somehow to morph a dress. But dress has completely different indexes...

The morph is projected - I don't know the details, but it seems to look at how the vertices of the figure near any given vertex of the drss have been moved from their zero state and then to move the dress vertex to match. This is an aplication feature, not a content feature - if the game engine doesn't have somethign similar you would have to provide the derss with matching morphs yourself, and have the game engine apply the morphs in both.

Thanks Richard Haseltine for explanation. I thought that it was all about math and you confirmed it )
