I’ve imported my Genesis 8.1 character from DAZ Studio using DazToUnreal plugin with a bunch of morphs. I can see morph targets when I open Skeletal Mesh under morph targets tab.
@Leomerya12 thanks for suggestion, unfortunately this did not address my issue since I am importing directly from DAZ Studio into Unreal Engine using the DazToUnreal plugin.
However, I probably found out what I was doing wrong. When I re-imported the whole character I noticed that animation curves list now contains all morphs until I re-assigned skeleton asset of my skeletal mesh. I was not aware that skeleton asset also has something to do with morph target curves and needs to be re-imported when I am adding new morphs to the character. I thought that with morph targets I am affecting mesh only so I kind of expected that the only thing I need to replace is skeletal mesh asset itself.
The reason I was using old skeleton is that DazToUnreal regenerates skeleton each time I import the character so I am loosing changes I made to it like sockets. So I was recycling old skeleton (reassigning it to the skeletal mesh after import).
