Animation don't find

I’m learning unreal engine 5.5, using a set with animations: Game Animation Sample | Fab

My character is lower than the one used in the set, so I made a retarget of animations and montage, correctly replacing the links. In PSS_Traversal, I set the skeleton of my character, and in PSD_Traversal, I replaced all the animations from the old skeleton with new ones. In CHT_TraversalAnims, I did the same.
In my project, Traversal is responsible for climbing on surfaces. However, when I try to jump on a surface, I get the error message Failed to Find Montage!
Could you please explain why this is happening? I have specified new animations in all the necessary files. The Action Type is set to Mantle.





can you tell me how you changed the character in this project, I haven’t been able to do it for 2 days due to frequent mistakes?

Do you mean retarget? You can do this by right-clicking on an animation or montage and selecting retarget
