Help needed: Mixamo to Metahuman retargeting not working in Unreal 5.3

Hey everyone, I’ve been trying to figure out animation retargeting in Unreal Engine 5.3, and I need some help from experts here. I’ve watched a bunch of tutorials where it seems pretty straightforward, just select the source and target skeletal meshes, hit retarget, and you’re good to go. But when I right-click on the downloaded mixamo animation sequence, the retargeting options I get are completely different from what I’ve seen in those videos.

As shown in the screenshots below, I selected the RTG_Metahuman retargeter, set the source as the skeletal mesh from Mixamo, and the target as my Metahuman. But when I check the newly created animation sequence, the Metahuman just stays in an A-pose instead of playing the animation. What am I doing wrong?!



Greetings @alifashf!

From your provided data, the steps you are following are correct. Retargetting from 5.4 onwards was made easier, if you have the possibility to upgrade, the following guide should resolve your scenario easily:

If upgrading is not possible for your project, here’s a more detailed process for 5.2:

Additionally, you could review the UE documentation related to retargets, to ensure all steps are covered:

Hey @brs-sebascova

Thanks for making me realize that all the videos I’ve been watching were for UE 5.4 and above. I actually had that version when I started my project, but I stuck with 5.3 for its stability and standalone ray tracing. Now that 5.5 is out, I’m considering upgrading. Do you think it would bring any benefits (besides the easier retargeting process), or is there a risk of breaking something in my project?

Glad to hear the data was useful for you! As for upgrading, the latest version is usually your best bet, as it has the latest features the engine can offer.

On the other hand, for my personal projects at least, I tend to stick to the previous iteration from the current (in these days, that would be 5.4), as those builds are the most stable, less prone to unexpected behaviours, and are also the most covered ones in documentation and videos when you need help or look for support.

Thanks for the quick reply! But isn’t 5.4 the buggiest compared to 5.3 and 5.5? Last time I used it, I had a pretty bad experience. But it’s been months, so it might have improved since then. Just wanted to confirm before upgrading my project!
