Texture Wont Apply

Hello guys i am trying to setsubmaterial on kleiner i have the textures i set a custom kleiner head i made (its index is 3) and it works perfectly
But when i try to set kleiner’ body submaterial (which index is 6) the texture is black.How can i fix this?

Are you subtracting 1 from the index? Wiki says for submaterial: you have to subtract 1 from them.
