Hey !
Thanks for bringing this up !
I'll log an rfe for this.

In tomorrow's Daily for Houdini 21.0 there will be a toggle on the APEX Unpack Character SOP that creates the name attribute on the output skin geometry.
Then you can wire those outputs directly into the FBX ROP.
Here's an example file.

Having a wrangle to update them does seem like a good idea.

Honestly, I was also initially targeting these layer attributes, but it turns out there's no information on how to read them. There's no information in the node help. No neural network knows either. The Detail/prim() functions return zero. Could you tell me how to read them in hscript or VEX?

You can use python to read them. hou.ImageLayer.attributes() will give you a dictionary with all of them.
