Thank you for your support and your professional guidance. I will seriously consider your suggestions and do my best to meet your requirements (I am currently busy applying for a PhD position, but I will update as soon as possible). However, before I make updates, I suggest that you refer to this for reconstruction results that include the neck and to this for results that include the entire head. I believe this shouldn't be too difficult, but please note that 3DDFA-v3 was not trained on scenarios involving the neck or full-head models, so accuracy outside the face area cannot be guaranteed.
Hi, thanks for responding. The accuracy for regions outside of the face isn’t really important. It’s that the cropped face model leads to rendering artifacts in the use case I’m researching. I need a full head model with proper UV layout to avoid those artifacts.
I tried using BFM-to-FLAME, but that repo doesn’t support this specific BFM.

Could you please describe your issue in more detail? If you need accurate UV mapping coordinates, I can provide them, but I didn't understand the difficulties you are encountering.
If you watch this video, you can see the process that I'm using: https://www.youtube.com/watch?v=uSxgt5mcbXM
When you unwrap and rewrap the UV Pass with the BFM, the edges of the face leave artifacts in the final image.
3DDFA-V3's head tracking is a lot more accurate than EMOCA, but the BFM can't be used because of these rendering artifacts.

I watched your video, but I am not very familiar with face retouching. Here are my suggestions:
Base Footage
Face Unwrapped
Face Re-Wrapped with artifacting around the edges of the BFM.
UVW Pass
When you use the FLAME model for this workflow, you don't get these edge artifacts.
Unwrapped FLAME 2020 model
Rewrapped FLAME 2020 model
We can mitigate most of the rewrapping issues here. The worst is around the eyes, but we can work with it.

Hello, have you solve this issue?
Not by a long shot. Try SMIRK for a whole head solve, and if you want it to work on anything but closeups/selfies, swap out RetinaFace (used here as well) for MediaPipe in the mediapipe_utils.py files.
Hi, Is there any way for this to output with a Neck?
EDIT: Ideally, a model with a complete head and neck.
Thanks, Eric
