Hello @sh.min,

**Welcome to the Convai Developer Forum!**

Sorry to hear you’re running into this issue.

Could you please start the scene and share a screenshot of the blendshape values under `CC_Base_Body` while the scene is running?

Thanks for sharing the details.

I’d recommend trying to reimport the character or testing with a different one to see if the issue persists. Also, you might want to check the Reallusion Forums for any known issues with jawbone rotation from CC4 exports.
