Morph targets on components

I’d like to set individual morph targets on components.

It all works OK till I set “master pose” then it looks like I can only apply targets to the master skeletal mesh.

IF is do this with names of morph targets that only exist in the component skeletal mesh, it works in persona but not in the game.

i.e. the morph target of the sub component is applied when applying it to the “master” skeletal mesh, but only in persona, not in the game.

Which behavior is right ?
