Have you ever figured out a workaround for the 'deformed eyes issues?as shown here this is up step to 10 and before exporting the character as an obj
and clearly has eye morph issues and top of the eyelids.
I run into the same problem. There are a bunch of characters that I tried to port and this is the main thing that stops me.
On some models it does not happen (or is acceptable) and on others it's a horrorshow.
The way I see it, the root of the problem is the fitting G2F to G8F is just not good enough.
Maybe they are better methods for this step in Blender.
