Can't create morph targets for skeletal mesh bones

Hello I don’t see a way to create morph targets for skeletal mesh bones(hands, legs, etc)
I can’t even use Set Bone Scale by name to change bones size in-game because it only works for poseable meshes. Why is that?
Please help how to create morph target or other ways to scale bones in-game

Can you please share how to import them correctly? My character might already have ones (mixamo)

I have a character with morph targets. But on import there are no Import Morph Targets option at all. I see the option exists but just not to me

I had the same problem.
Are you using 3dsmax? Try to put the “Morpher” modifier after (above) the “Skin” modifier.
