Please help my object is transparent {Solved}

Hi,

I wanted to make a bed with a separated frame, blanket and pillows.

I've isolated a Maxis mattress (that I'll use with bedding recolors) and it's working fine. 

For the frame, I used a rug to be able to place it without bb.moveobjects on. (I wanted to do the same for the blanket and the pillows)

Here's what my model looks like in Milkshape and S4S.





And here's what I get in game.. the texture is very weird. It's transparent and some parts of the model are not showing.

Besides, I can't place it indoor without using bb.moveobjects on.










I tried to find an answer on the forum and I've changed the textures many times, exported DDS both with DXT1, and DXT5 but nothing works.

I don't understand also why I get the weird shadow. I've replaced the shadow LOD with my model.

Please can you help me, I've spent so many time on the 3d model, it's very frustrating to not to see it in the game..

Here's the file if someone want to take a look : Download

Thank's in advance for your answers, I hope that I'll not have to bother you too often..
