@Bassline303, I'm trying to send over characters from iClone to Unreal Engine 4.26.2 via LiveLink, the process starts, the transfer command prompt starts but then half way through the process it just crashes and shows send and close or send and restart. Choosing send and restart button throws errors. 

Have tried re-installing Unreal Live Link as well as iClone but not avail. Need help!

It works fine for me.

Correct !  Works fine here too.
UE4 is opening a second UE4 instance when transferring , so if you get any errors , just close it ... the main UE4 project should still work fine with the transferred Character.

Thanks Bassline303 and Robert,
The characters transferred alright but when I activate the livelink in iclone the characters in UE4 are not connecting, LiveLink in UE4 is active and shows the characters but, playing the animation in iClone with the LiveLink active, doesn't transfer the animation over to Unreal Engine. Never had this problem before, Not sure what and why its doing this?

I have a fight sequence to animate and its easier to do it via livelink and record with Take recorder to get the placements properly I thought as doing the animation in approximation and then transferring via FBX screws up the positioning in the environment for the actors.

Thanks Robert,
Will double check the version again. Reinstalled LiveLink via Reallusion Hub as well as reinstalled the LiveLink plugin for Unreal Engine earlier today.. Will check the versions as you have suggested.

Is your livelink activationa nd animation working from iClone to UE4? The characters transferred and show up at the iclone origin point in the environment, but activating the link in iClone's Unreal LiveLink plugin doesn't activate them despite LiveLink in UE4 showing the link is active.

Live link activated in UE4 ? Green dots?

Here is an easy way to record with Take Recorder :

I assume that they have set an Iclone Origin
Yes it works for me
Check if your character names match.

Hmmm! You are right, I'll check first thing tomorrow morning. When we transfer characters from iClone, the name should be the same shouldn't it. Although I named my character Hammand Camp Fight in iClone and I remember in UE it was converted to Hammand_Camp_Fight.

Maybe I just need simple naming convention. Will come back to you. Thanks!

Yes Live Link is activated in UE4 but still was not streaming with iClone Link Activated. Will redo the process again tomorrow.
Can I change the name of the character in the project or do I need to redo the process of transferring from iClone all over again with better naming conventions.
