@anle01637: The game is using retargeting for most animations, thus animations found via animation search can be incompatible with particular mesh, it's better to append and export only compatible with the mesh animations manually. Also some animations are additive ones - they're not supported by umodel directly and they're not marked such in UE5 build (respective property is not parsed). There are two topics on the forum with helpful info about additive anims, related to umodel,
first and
second. If only rotation looks wrong, you can try to use "adjust anims" option, brief explanation for it is provided
here.
