game_motion orientation and translation

[shihusi]

I found that there are errors in the orientation and position of the smplx actions in the game_motion dataset. The rendered images show the human figure at the edge of the frame with the head pointing downwards. How can I fix this issue?
Additionally, I would like to ask the specific definition of the first three dimensions of orientation. I have tried Euler rotations; single-axis rotations work fine, but the results of multi-axis rotations are not ideal.
Thanks in advance.
