Issue 12152
IC8 hangs transferring motion file to Unreal Engine 5.5
When attempting to transfer a motion file longer than 1 minute through the Unreal Live Link panel, IC8 hangs and becomes unresponsive. Only motions/animations under 1 minute can be successfully transferred to Unreal Engine 5.5.

This issue does not occur in IC8.54.

Hi... i am also having this problem... but in my case (and sometimes) the animation will port to une 5.6 but it takes a very long time... the file prior to updating iclone and cc5... would be super fast...

Hi,

Here's the YouTube links comprises of video's recording of the issues;

1) Motion Transfer IC8 - UE5.5 - motion clip 30 seconds
https://youtu.be/VWNBupkFfMY

2) Motion Transfer IC8 - UE5.5 - motion clip 60 seconds
https://youtu.be/BGNH5cKb60M

In the 1) IC8 successfully transfer the motion to UE5.5 but in 2) IC8 would usually stuck in the 30% mark and from there it'll hang and not respond and needs to close program. So there seem to a problem transferring motion files 1 minute or longer animation clip. In previous IC8.54 I could transfer motion files up to 3 minutes long with no problems. Attached are the links to the IC8 and Unreal engine project files:

Thank you
