Not Reproducible
Issue 12318
Bones get twisted when generating a Biped rig.
1. Exported the file from CC4 and imported it into 3ds Max using CC Auto Setup.
2. Created a Biped rig.
3. Loaded a BIP animation.
4. The neck and finger bones become twisted.

**Possible Cause**
The default finger rotation axis for Biped is the **Z-axis**, but the Biped generated through CC Auto Setup uses the **Y-axis** as its rotation axis.

Hi multics777,

First and foremost, please accept our sincere apologies for the long delay in getting back to you.

Thank you for the detailed report regarding the twisted neck and finger bones when applying a BIP animation. We also really appreciate your technical insight regarding the rotation axis difference (Z-axis vs. Y-axis)—that is incredibly helpful information for our team!

Since it has been a while since your initial post, we have released several updates. Could you please download and install the latest version of the CC Auto Setup for 3ds Max from our official website to see if this bone alignment issue has been resolved on your end?

If you find that the bones are still getting twisted with the newest version, we would love to investigate this further. To help our developers replicate your exact environment, could you kindly provide:

    1. Your Files: The specific character file you exported and the .bip animation file you are trying to load.

    2. A Screen Recording: A short video showing your step-by-step workflow, from generating the Biped rig via Auto Setup to loading the animation data.

You can upload these to a cloud drive (like Google Drive or Dropbox) and share the link with us here.

Thank you so much for your patience, understanding, and for helping us improve our tools!

Best regards,
Kayla
