Head not moving with expression (importing Digital Soul clip from Iclone).

After trying stuff and debugging for 2 whole days and 3 claude code chats, here I come.

I know there’s a similar post below, it’s a different problem.

I’ve imported in unity an animated expression coming from Digital Soul (a paid pack containing head and face movements) exported from iclone.

On iclone the eyes move, the head moves. In unity, only the face, no head movements.

I succeed to play the animated expression on all cc characters on my scene (camila and the 2 default most recent cc5 chars). Now issue is that head / gaze ain’t moving even tho rest of the face is moving.

There is this script called Bone Driver on the characters. I turned Drive Head on.

I’m running into very strange inconsistent results, sometime when I hit play it works sometime it doesnt, sometime it works for certain characters.

I succeeded to make all expressions animations move head for one character once, so I know its possible. But even tho all the other characters had exact same settings, the animations didnt move their head.

Problem goes for both in humanoid and generic rig.

unity CC/iC importer settings (are they reapplied everytime you hit build character tho? or I have to do something else?) :

Hi enlairlepouce_59,

Could you kindly record your workflow and send the video to winnerhung@reallusion.com, or share it via a cloud drive link?

We tried exporting a CC character with the Digital Soul expression through the Unity pipeline. The head-turn animation works correctly because it is included as part of the facial expression and is successfully transferred to Unity. Please see the attached video here

We’d like to compare your workflow with ours, so your screen recording would be very helpful.

Thanks

Thank you for your answer. The issue is actually when using multiple cameras change (and maybe because im with cinemachine). Bone driver script wouldn’t work for characters not in the main camera field before I launched. Now fixed, there just cant be 2 main cameras I think

Hi enlairlepouce_59,

We have confirmed that the issue is not related to the camera and that the head animation was exported correctly. It may have been a coincidence that the head animation worked when you used the camera.

We are not familiar with the Bone Driver plugin, but we’re glad to hear that everything is now working properly on your end.

Regards,
