There are definitely some differences in the MC model in the in-game images. There are many such images, I will only give a few examples:
The bullet wound scars started appearing after a new Daz asset became available, so they weren’t in earlier scenes, and I haven’t bothered to go back and fix the earlier renders yet.
I’ve forgotten them in a couple of newer scenes, but it was a deliberate choice not to include them in Emma’s dream, as that’s her image of him, not the real him.
I completely forgot his tattoo in the Kaylah sex scene, but I’m currently redoing that scene, so it’ll be fixed in the next release.
And in the MC’s combat flashback, he hadn’t been shot yet, so no marks.
