Hello, I am a student from the University of Science and Technology of China (USTC) and am very interested in this project. However, when I attempted to replicate it, I found that the BVH files produced by A-GPT caused character jitter and abnormal foot-to-ground contact after being imported into the engine (but the animations on your website appear to be more stable). I would like to ask if you have made any operations related to the integration with the engine? Thank you!

Thank you for your interest in the project. There are indeed some issues with the generated animations:

  1. The SMPL-based skeletal structure is incompatible with skeletons in engines such as UE5, so you may need to retarget the motions, some smoothing and other post-processing..
  2. The animations generated by the algorithm have foot sliding problem. The animations displayed on the project homepage have been post-processed, and related tutorials can be found in the QQ group: 160682595
