Just my personal opinion on the matter
as animated filmaker who makes my own clothing/prop content
and renders animated CC3 Avatars in Blenders realtime EEVEE engine.
Right now Daz and Reallusion are competing ,Character generation eco-systems.
I personally feel that the CC3 transformer to import your favorite
Daz shapes & base skins/clothing/hairs is about as generous as Reallusion needs to be
with helping Daz $$sell DAZ store content$$ to Iclone users.
Particularly considering the fact that this thread/subject would
assuredly be promptly vaporized from the Daz forums as the features of CC3
are a strictly forbidden subject over there.🙄
As you may know ,the CC3 transformer does not literally "import" your Daz genesis figures
but merely creates a reasonably accurate CC3 Avatar Dopplganger, via shape projection.
The CC3/Iclone avatars are built to a uniform standard so that we can have 100% compatibilty
with ALL of the current Iclone native features basic&optional
(Live face headshot,lipsync,facepuppet etc).
The Daz G3/8 face/expression morphs would not work with our native facial animation system.
in fact Daz G3/8 figures are not even fully compatible with Daz's own nonlinear motion clip system
aniMate 2.
Daz studios native audio based lipsynch system is only available by installing the 32 bit version of Daz studio
the 64 bit options are expensive third party plugins including "mimic live" which does not even support prerecoded audio tracks
only live microphone recording.
Thus I see no reason
for RL to "update" OUR core software to support the morphs of a third party figure who's development
cycle they do not control, when Daz themselves have not bothered to with G3/8 and their own Daz studio.😌
Daz has their own means to export figures to the game engines and other 3DCC's
and we have ours.
I personally believe you should stay in one Character eco system for maximum pipeline compatibilty
but we have the option of using both with (some extra work of course)
And IMHO Reallsuion's is superior and it is part of Reallsuions game dev business model
to give priority Reallusion Avatars connecting to those engines or 3DCC's..not Daz's figures .
I personally dont use game engines as they are only as good as the content
you import and I create my own content in Blender where I have a realtime engine.
However, I am thrilled that the CC3 Avatars, I export to Blender, come over
with the face morphs as animated Blend shapes that are accessible with Blenders Advanced
Curve/Graph editor.
