Issue with retargeting in UE5 5.0.1

hi everybody, i’m struggling with retargeting, source material from mixamo and destination metahuman: Ik rigs and ikretargeter are perfect:

but as soon as i create a retarget animation i obtain this:

it seems that bones are not scaled correctly, i’ve tryed everything from the web, transition mode on globally scale for root, disable post process on the skeletal mesh, but anything worked.

is it a bug or i’m missing something?

SOLVED, but using the “send 2 unreal” plugin for Blender.

it appears that somewhat the plugin managed to correclty apply scaling to some components that were corrupting metahuman proportions, even if i’ve checked all the components and bones one by one.
