Blending and getting an individual texture from a face

[farshizzo]

When applying the texture and fragment program, specify the sub-node that the skin texture is applied to. For example:

face.apply(blend,'skin_geom')
face.texture(tex1,'skin_geom')
face.texture(tex2,'skin_geom',1)

You will need to replace 'skin_geom' with the actual name of you skin sub-node.
