IClone is useless without the ability to export.
Not really a fair assertion.
I personally render everything in Blender.
But most here operate entirely within the Reallusion eco system
and don’t need to export with Blend shapes.
Just FYI
the .obj that you exported from CC3 basic can be rigged with the FREE Accurig tool and exported out as FBX where it will have an Actor core compatible rig.
You can use the free Blender pipeline tool
to import it ,convert to rigify and apply any actor core motions to it inside blender.
No facial animation blend shapes , of course,
However it may be useful for non speaking Characters or costumed Characters wearing masks. helmets etc.
