Thanks Sza! Always a treat to read your comments!

No, they come from the HD details of DO Freja 8. I did the base morph and skin.

Cool, I was going to see if there were any tricks that could be shared. I'm working on my first model where I need custom normals and its been a...thing...to say the least.

Ah OK... If the scar isn’t too deep or extreme,
you can bake it into a normal map and reuse it on the base mesh in DAZ.
To do it, I would use Blender with an addon from diffeormorphic (Daz importer).
I still have a copy of Blender 4.0.2 with this 1.7.3.1938 addon installed.

In Daz, I would start from my bare model in the default pose (no eyelashes, hair or anything), export
it as 2 obj files:
1. as base, 2. as HD (subd3 or more).
For the export don't collapse the UV tiles.

Now in Blender...
Import the HD, shade smooth, sculpt the scar with the Blender sculpt tools.
Import the base, shade smooth.
Save as a blend file (important).

In the right panel (N-panel), you will see Daz Setup:
you can go to submenu advanced setup, then hdmesh, where you will see multires.
You can click on it after selecting the low poly model and shift-selecting the high poly one.
Then select the low poly one and click Bake Maps (you will be proposed displacement or normals,
2k or 4k etc). And your maps are computed (in my case they are automatically saved
in Documents/textures/normals/...).

You can go back to daz and put the created normal map at the right place in the surfaces tab.
You might need to edit it in gimp first if you are only interested in the scar.
Hope this helps...

Awesome, thanks! Will give this a go.
