About rotationt replacing the Jacobians

[zbdehh]

Very good result.
When I tried to reproduce this paper, I found that the Jacobian matrix was cancelled in the v3 version of arxiv. I canceled the Jacobians and got very worried results. I would like to ask if you use the Rotation parameter to replace the Jacobian. Also want to know if the code will be open source in the near future?

@begins233 I'm trying training without the Jacobians. It looks fine so far.

@zhanglonghao1992 Thanks.
There may be some bugs in my code, I will check the code again. This is my current result. The left is the output, the middle is the output with no expression coefficients, and the right is GT. Have you ever encountered such a situation where the posture is correct but the face is expressionless, I hope you can give me some suggestions, thank you.

@begins233 It looks like there's something wrong with your implementation.

Thank you, I try to keep checking my code. Hope you can open source as soon as possible.
