In my previous post I highlighted how removing the LODs and forcing a rebuild cause significant differences in the face of your Shepard. I also mentioned attempting to automate the process of copying the ME2 LODs to ME3.
As you can see, I think it's been a real success. I think the character of my Shepard really shines through.
Seriously, I think this illustrates that the ME3 head morph is actually more complex than it's previous iterations. The data is there and I think the internal knowledge that Bioware has could easily transfer the nuances that lie somewhere in this collection.
