Is the Unreal Live Link broken for Unreal 4.26? 

I decided to try out the the provided Nick character. 
He transferred to Unreal no problem but his CCLiveLink_Blueprint is giving me errors.

I have not installed the recent update to Unreal 4.26 yet. Could that be it?

Update - Ok after applying some animation files via Iclone it does seem to work,..
Should I still  be concerned about this error then?

I'm having the same issue. I can transfer character from iclone to unreal 4.26 through LiveLink  no problem but as soon as i press "activate link" in iClone the charater turns into a mess in unreal with body parts completely distorted. Did you find a fix?

Livelink is fine for 4.26 just make sure that you have the proper versions installed. Uninstall everything and Install the latest versions from the reallusion hub
