For example, I just found out about 'Grab-It' add-on priced at US$25.
This addon does the same and it is free Free Dynamic parent addon
And I personally, absolutely, would NOT pay for any external remesher/retopo software for Blender has Blender has several
Built-in options for remeshing and converting tris to quads.
“Maybe it would be easier if I can just import the clothes into Character Creator 3 and do that process there.”
If you are not skilled at modeling in Blender, I think using your existing CC3 pipeline to harvest clothing meshes would be the easiest for you .
Keep in mind that your final destination is UE5 .
So choose your Blender native options carefully based on how they
will eventually have to translate over to UE (presumably via the iclone Live link?)
My final destination is Blender.(EEVEE and Cycles)
However I do still use my iclone 7 to quickly cobble together many base layer root motion clips
and export ,via CC3 pipeline ,to retarget to my ARP rigs as ARP has a built in profile for the CC3 motion
Data imported as FBX.
I no longer use Iclone ,or CC3, for anything other than this.
All of my “Star” front camera ,speaking characters are high quality Daz Genesis 8 models re-rigged with ARP
while retaining their Shape key, Audio based facial & lip sync ability, via the free Diffeomorphic Daz to Blender Addon.
Any non Daz figure I may grab from sketchfab,Poser etc can be rigged with ARP in minutes and still use the same Iclone/CC3 motion data as my Daz genesis figures.
as well Motion data from my Mixamo or perception neuron& rokoko mocap suit data etc .
And ARP has a rock solid rig prep and export tool for Unity & UE5
Thus I do not need Accurig stand alone or Accurig advanced (in IC8.1)
or any of the Actor core motions.
At this point ,Blender with ARP($40) and the animation layers add-on($29) is a complete universal Character animation system
on par with the mighty Autodesk Maya & Motionbuilder
All for less than $100 USD.
