Hello Mike,
How did you get this texture, BTW?
We need to assign G8 materials because G8's Surface "Torso" is the combination of G81's "Head" and "Body". CC3's transform script likely reads only one texture as "Torso".
That is why you need to merge G81's Head and Body in Geometry Editor, then rename it as Torso, and Assign a G8 material, if you want to bake textures in CC3.

Hello - Luciano is correct, you can rename node and transfer in, with the emulated shape.  It will require some tinkering:
What I find though with my tested Victoria 8.1 is that the Eyelashes and Tear duct also need to be arranged beyond the simple node rename, as they come in as unattached geometry.  Renaming the respective node does not fix them, so eyelashes are missing.

Without working eyelashes this seems to make the whole thing an explorative case-study, versus an actual solution towards use.  Unless, that is, eyelashes are not needed in the character.  

Sorry to come back here so late but been SO busy with other things.

As Tony says, eyelashes are a problem.  But also textures -- the textures I got were from an 8.1 character as well, just not a "normal" one (which, like eyelashes, will happen a LOT.  Let's face it, we really don't need the skin, much, if the character is just any other character.  Where we need the skins are from those that are definitely NOT the normal run of the mill stuff, and they don't follow those same patterns).

So, yes, this is more of a sort of "idea" than an actual workflow to get an 8.1 character inside of CC3.  It will need a LOT of work by the RL devs in order to get this working properly and they have a ton of things on their plate right now.

To further elaborate, neither the Storybook Turtle (the one I posted) nor the Storybook Mouse (both designed for 8.1) will work with this method.  The morphs come across just fine, but not the textures.  Same with the Nanny Bot.

Again, textures ain't that important if we're talking about run of the mill avatars.  We can use the CC3 textures for those just fine.  But for the stuff you REALLY want to get over from Daz you need textures that will NOT transfer this way (and I have no idea how you could get it to work - it's way beyond my pay grade.  Even SkinGen doesn't handle them).

AAAAaaannnnddd to finally put this to bed...

The reason the "trick" (and that's what this is) works is the UV maps are changed to accommodate the "regular" 8 figure.  All well and good if your materials are for just a normal avatar but this is NOT the case for most of the ones we'd like to bring in (again, we don't need just normal Daz figures.  We can make PLENTY of those ourselves.  What we need are the more odd ones that CC3 does not have).  Most unusual Genesis stuff has different UVs that can't be remapped this way.  So -- no way for Transformer to handle those.

Note that Transformer DOES correctly handle odd UV maps from other Genesis figures, just not from 8.1.  I assume that's because 8.1 uses a different UV mapping process entirely and it can't be converted.  So I would advise folks to give up on getting their 8.1 figures in.

Hello everyone, sorry for my late reply. 

I agree with Mike, I would rather try converting UVs only for special figures, so we don't really need basic ones. Btw, RL nailed it by improving integration with Blender and Unreal  Engine.

For me, I transfer my old G2 and G3 figures as head morph templates for Headshot, grouped by ethnicity, so I can quickly adjust custom characters. 

Cheers,
Luciano

As AD correctly mentioned, Daz did make an announcement....it reveals nothing content-wise, nothing render-related, nothing figure-related.  Just install-ish type stuff.

https://www.daz3d.com/forums/discussion/506346/daz-studio-5-development-update

As RL doesn't rely on any plugin and just takes a Daz export and then imports it in, it will be interesting to see how the RL team can incorporate this into a CC4 Daz Transformer.  Hopefully CC4 will benefit from a higher set of HD components so that any future Daz 5 figure can be brought in at its full glory.
I don't know why Daz would be hostile to RL users, as they would buy their content to use in RL products....but I think competition will heat up even more now as this now goes to MetaHumans....

With MH, Unreal opened the door but is just sitting on it.  And, they don't care to compete with Daz or RL, they just want game developers coming their way.  So this opens up a huge lane for Daz and RL to make the most of a MH-level figure that can interact with the MH components of UE5.
Both Daz and RL have plugins exporting to UE, so this is where the plugin part really comes into play now, because if Daz comes up with its own MH Transformer modeler thing, it could knee-cap RL's progress.  "UE5"..."Daz5"....see the marketing here?
But, RL can knee-cap Daz right back with its Daz Transformer, which in this scenario could allow an RL user to combine MH + Daz + CC4...the "ultimate" package.  
PS- Youtube has exploded now with MH users using AccuLips, so RL has quite nicely injected itself into the MH Hype!  RL has everything to gain by keeping Daz Transformer in development, we know not what yet the future holds!  

DAZ has a funny way of putting it. "All plugins and some scripts will be broken" "I hope everyone is just as excited about DAZ Studio 5 as we are."  :P

I'm quite impressed with the way RL has been strategizing by connecting iClone to Meta Humans via Live Link and thus providing facial animation and lip-synching to MH. Can DAZ offer that?

RL seems intend to position themselves as a serious 3D toolmaker, so I think that's good for the future.

The only thing missing is a Mac version, but I don't know how important that is.
