I am having hard time to make this work
I did export Aiko3 and Aiko7 from DAZ studio; I use transformer to import the figures, all works fine. Until I save the preset.

This is how it looks when I start a new scene


And this is how it looks like once I import Aiko3


Then I save the preset as custom preset, so I can load it again at later time


At this point I would expect to see the preset loaded if I start a new project and click on the preset, but what I get is nothing like what I imported.




As you can see, it does look nothing like the imported preset. What is going wrong here?

Avatar preset includes morph slider data & skin textures.
To use Aiko's morph as a library, you have to create morph slider first. 
1. Create slider (source: neutral base; target: Aiko avatar) (manual)
2. Apply the newly created slider on the neutral base
3. Save the avatar preset

Ok, this doesn't seem to be explained much anywhere.
I saw some videos on your youtube channel that show clothing mods and then the instructor would press the + sign to add them to the library. I assumed that was the same principle when loading morphs.
My assumption was validated by the fact that the new avatar with the morph applied was saved, and a thumbnail saved; so I thought that this was the actual workflow.

Will try your steps now; thanks for the clarification

I did export from DAZ as FBX, not as OBJ, and the morph accept only OBJ
This does not seem to work. When I export as OBJ from DAZ, I don't get an objkey, which is required by CC3 to add a morph.
I am not sure how much more complicate this process can be, considering that all that is expected is to save the morph as applied from transformer.

Thanks for the clarification; I was not sure if there was something that I was missing.
I tried your workflow and there is a problem when I try to reset. I can't reset the figure because the reset button is greyed out, once I apply the Aiko3 via transform and create the slider for the morph.
So I can't set the figure to the neutral base, to then apply the slider value. I tried all the options but no luck.
Is there a bug that does not allow the reset button to work, when a transformer character is applied?

Start a new project, or load the embedded female or male character. Then click the reset button.


It's not a bug. 
To perfectly transforming Daz/Poser character into CC, the Transformer tool resets the morph data during the transformation to keep the body shape.
Which means that there will be no morph data on a transformed character.

Oh, I see, the slider with the morph is saved in the app even if you reset the project. I thought it was saved at figure level, not at application level.
Getting progress; I can apply the morph but the teeth and face are quite off; the body too is distorted quite noticeably, when I apply the slider to 100%, compared to the output I get right after applying Aiko3 from transformer.

I think I tried all the various iterations and the teeth continue to be sticking out no matter what I do. For some reasons the morph when using the slider, does not account for the teeth, although it is correctly applied when using transformer.

This looks a bug to me; unless there is a step that I am not aware of. I do get the same results either if I start from the standard female figure when I create a new project, or if I reset the morphs on the figure, before apply the slider.
Thanks

I guess it is time to fire up a support request. Thanks for the hints!
