Pelvis scale problem when sharing animation between 2 skeletalMesh with the same skeleton.

Make sure that NOTHING is scaled in your 3D app.
Everything has to have a scale of 100% or 1.0

Of course, it’s the first thing I tried

It looks like you’ve found this bug: Skeleton root bone scale incorrectly set to 1 in animations after "Imported bone transform is different" error, resulting in smaller/bigger meshes in animation - Character & Animation - Epic Developer Community Forums

*The skeleton root bone has 100 scale in the skeleton view.
The skeleton root bone has 1 scale in the animation view. This is a bug, it should be set to 100 like in the skeleton view. Because of this the animation is tiny.

It’s exactly my problem !
But I work with 4.15.2 version of UE and as I use the exact same skeleton, I had no “Imported bone transform” error. I just use the SK_mannequin skeleton.

Did you find a workaround ?

I didn’t know where my original 2.54 scale on root come from…
When I open a brand new project and check the bones’s scale inside the SK_mannequin skeleton and every bones are 1.0 scaled.

So, I restart at the beginning…
I clean every file from my project (mannequin and my_custom).
I migrate the original SK_mannequin from a new TPP project.
I check the scales for bones in the new SK_mannequin skeleton and they are all set at 1.0. Perfect !

I import my_custom_SK and boom, the root bone in the UE4_mannequin_Skeleton is now set at 2.54 scale…
