Attached Link: Need help ! Same old problems

I'm trying to make a cupboard/cabinet. I build 3 objects in MAX, the frame and two doors, export as obj. I put them in the UV Mapper, made textures and so on. I imported them in Poser, put everything in place, put on the textures, moved the pivots to the corner of the doors and made the doors child objects of the frame. Now the problems : I seems impossible to make a prob of it. I have 3 parts, hierachy and so an. Ok, but I can make a character of it. Sounds great but won't work. If I do so, I loss the textures, the hierachy and the pivots move back to the center of the objects. Whats wrong ? Is there an essential step I'm missing ? Is it possible to make probs with hierachy and moveable parts ?
