This model was built by my firend with Maya, but it has some errors after importing to MED.
From the engine preview:

1. The alpha channel seems does not work with his hair, I use 32 bit-tga,here is the link for tga:

2. Look at the back of his shield, double face texture doesn't work. Do I need a shader or I can fix it in MED?

Forget the wrong normal map with his right leg, I know how to fix it, but please help me fix problem 1 & 2. Thanks.
