Problem with new models | Autodesk 3DS Max

[Steph12]

Hi guys, i've started modelling today and now i have a problem.

I've created a quader in 3DS max and gave it a texture.

But when I load it in MTA it only shows 3 sites of the quader, the other sides are invisible.

I don't know why this happens.

Has someone got an idea?

By quader you mean a box? Before you export a model, make sure it's "Editable Poly" or "Editable Mesh". Also, make sure it doesn't have any flipped faces. Right click the model, go to "Object properties" and in "General" tab make sure that "Backface cull" is checked. That's all I can think of.
