Texture bug on every body part

[adepreis]

When a texture is applied to each Geometry rendered, it didn't displays correctly.

Maybe it's not a bug, just a wrong use of the shader but this texture works on a single Sphere in an other project..

Following the 6fc7631 commit, the wrong use of the shader seems confirmed because the texture works well on an object of the scene (background wall).
This error may be caused by a vertices-normal invertion in the shader but this remained to be confirmed.
