Can different mesh part share the same texture?

[falconcool]

Hi,I'm makeing new decoration items on character's faces,I succesfully registered it as extra head part and assign it as

facial hair in C/K's Race>face setting.It shows succesfully on C/K and nifskope.

I combined it's texture with vanilla's face one,because it's not too complex stuff,,it's all okay until i enter the game.

It's just doesn't show in game.

I set BSDismemeberSkin Modifier as "Head2" does anyone know what's wrong with it?

Thanks in advance:)
