Warning: PoseAsset XXX is out-of-date with its source animation

When playing or packaging in UE5 I am getting errors like this:

Warning: PoseAsset XXX is out-of-date with its source animation YYY

What does the warning mean and how do I fix it?

same here.

Do you use a MetaHuman and assigned the Skeleton to the UEMannaquin? Since that I get errors and warnings. While packaging it also get an error because it is saying the PoseIndex is not valid (happening in an if-statement in the Pose Driver).

Yeah, I am also trying to use MetaHumans. I have retargeted UEMannequin animations on to the MetaHuman Skeleton.

I also have the same problem. There seems to be a way to resolve it. Go to your pose assets (the ones in the warning) and under Asset Details → Source Animation there is a button right of it where you can update source. The problem is it crashes randomly so it takes forever to update all sources. Therefore I just removed the source animation from all the poses and the warnings were gone.

I had the same issue, on over 500 poses, so fix them manually was a no go for me
I did instead a quick blueprint batch to do the job automatically, I past it here in case someone else need it
The main hint here is that the broken poses has an associated animation, sharing the same name with just a different post-fix: _pose for poses and _anim for animation source

So, here the blueprint

It is an AssetActionUtility, called by right clicking on all the poses assets → Scripted asset action

Hope it helps

This is great, thank you. I had like 800 metahuman files to fix and this solved my problem.
