I am trying to retarget 2 animations from the animation starter pack to the UE5 mannequin. I can easily use these animations with Manny and Quinn by setting the two skeletons as compatible. But if I move the animations and meshes to a different folder, the ue4 anims no longer work with the ue5 mannequin.
Do I seriously have to learn about IK retargeting to retarget the anims even if Im not even using IK? Is the UE4 way of retargeting not a thing anymore?
If the animations work fine and only fail after moving to a different folder, did you try to fixup redirections in folders?
Not sure, what is going on with your project exactly. Analyzing Lyra's Animation | Inside Unreal - YouTube - this one has an excellent explanation. Here, a categorization is done into basically 5 differenct cases, when to use which options basically. IK Retargeting is the last of the options if everything is different, like mesh hierarchy, ref pose, skeleton asset, extra/missing bones…
Fixing up redirectors did not help. I eventually was able to move the folders by doing an advanced copy, but still cannot rename them.
