Hi,
it was successful twice however more than 10 times Unreal crashes when i try to export the animation using CLO Live link. It is same file so not sure 2 times was successful but the rest export tries were end up with Crash.
This is the crash report. I dont understand what this means. Any help? Thank you!
Hello, @pnrer
It seems like you’re encountering a recurring crash issue when exporting animations using CLO Live Link in Unreal Engine. This can be frustrating, especially when it interrupts your workflow. Here are a few steps you can take to troubleshoot and potentially resolve the issue:
Check for Updates: Ensure that both Unreal Engine and CLO Live Link are updated to their latest versions, as updates often include bug fixes for stability issues.
Review the Crash Report: The crash report may contain information about what module or process caused the crash. Look for any file paths or error messages that could indicate a specific problem.
Resource Release Error: One common issue mentioned in the forums is a FRenderResource being deleted without being released first. This could be related to graphics resources not being properly managed. Make sure to release any resources you’re no longer using.
Graphics Driver Compatibility: Notes are suggesting that setting Targeted RHIs to DirectX 11 instead of DirectX 12 may prevent graphics driver crashes in Unreal Engine 5 when using LiveSync. Check your project settings to ensure compatibility.
Simulation and Animation Settings: Ensure that simulation and animation are turned off in CLO and set in either Simulation mode or UV Editor mode before attempting to press the Update button.
Network Configuration: If you’re using a basic setup, UDP Messaging does not need to be modified for Live Link Face to work. However, if you’re on a LAN or subnet, resetting the Unicast Endpoint to 0.0.0.0:0 and removing any Static Endpoints in the Project Settings might resolve network-related issues.
If these steps do not resolve the issue, Please tell me I am happy to help you.
Best Regard,

Thank you @ryan1969manus for the reply! I am using 5.3 (5.3.2) Looks like that is the latest version for 5.3 . I work with that version cause looks like CLO/MD live link currently works with 5.3 version not 5.4. My Graphic card is RTX 3080. I also updated my graphic card through Nvidia. I tried both DirectX11 and 12. Interestingly sometimes works with 11 sometimes 12. But i am having crash issues on both.
MD/CLO Link works when i use it from CLO to Unreal but crash happens from Unreal to CLO. Out of 20 only 2 times it worked. The rest was crash or/and freeze issue.very annoying 
I have couple questions regarding your comments. You said “This could be related to graphics resources not being properly managed. Make sure to release any resources you’re no longer using” I already checked manage 3D properties in Nvidia settings and everything looks fine there but can you let me know any other way how i can check if it is properly managed?
My other question is, i already shared the crash report above . Where else i can find other crash report information? I checked Unreal program files and my project files but couldnt see there. Not sure where i can access that.
Thanks again for the help offer.
@pnrer for me it worked when I added material to my metahuman skeletal mesh before using livesync to import animation to Marvelous
HI, it seems that the bug of CLO live sync is more serious that I thought. I tryed everything and of course I rend the answers you gave and applied them I free space I upgrades for a stronger graphic card , there is nothing to do. I am about to do a project that requires a lot the use of clo and of course of live sync if the problem is not fixed I will have to cancel the project. Do you know if the plug in for 5.4 is available soon? Apparently is available from the Clo 3D side but I don’t find the place where to paste it and there is no substances plugin for 5. 4 anyway so it will not work properly either.
Currently going through the same issue… have you found a solution?
I am experiencing it using UE 5.4.4 and CLO Livesync version 1.1.3 (eventho in ue plugin list its 1.1.2) and with MD version 2024.1.129
However downgrading to UE 5.3.2 and CLO livesync 1.0.0 and also MD version 2024.0.107 made everything works.
So I reckon it is either UE or Livesync or MD is buggy (obviously)
I have the same error in EU 5.4.4
Livesync version 1.1.3
MD 2024_1_129
RTX 3090
128GB memory
4tbNVME SSD
Has anyone found a solution yet?
I also facing this issue too. I am using Unreal 5.3.2, tried CLOLiveSync_1_0_1 & CLOLiveSync_1_0_0.
both crush when i am just click the Bring Avatar & garment button
I follow this https://www.youtube.com/watch?v=_iO8Ob-5GHw video, and i never get pass the step at 13:00 step…
i have tried to arrange the UV map first and tick "Unified material " when i click the Bring Avatar & garment button on the plugin mode then it can be load until 20% then it crush again.
I keep searhing the steps i might missed which the video might not be mentioned.
May i know how you do if you are successfully finish the loading/
My CLO file with a substance texture, i tried to deketed the texture but it also happen again…
Thanks all
I have talked to the MD support and the solution worked for me.
We fount that this is a problem that occurs due to duplicate SkeletalMesh when sending MetaHuman data from UE to CLO/MD. It can be resolved by following the steps below.
- Open the Animation Sequence asset editor in UE that is causing the issue.
- Delete one of the m_med_unw_body entries in Preview Scene Settings → Additional Meshes → SkeletalMeshes. Please check the attached image for a reference.
