Incorrect loading of a 3D model (.3DS) on an Android device - what's the problem?

Question

Android

Hey! When loading a 3d model (.3DS) on an android device, all elements are not visible. Created and then exported from Autodesc 3DS MAX 2013. The models that I downloaded before are displayed correctly, I think I somehow exported incorrectly. What could be the problem? What are the features of creating 3D objects for their subsequent use in mobile applications?
Thank you.

I figured out that it is necessary to convert the model to an editable mesh before exporting the model. Right click on the model (before that I grouped all the elements) - Convert to - Convert to editable mesh. It seems to be as necessary for the binding settings, grid construction.
