after exporting my model from 3dsmax as 3ds, the vertices become unwelded, whatever i do. As i import this model to

Gamestudio, the model looks just fine but the mesh tester in med informs me that it is opened. So to close this mesh, (to

weld the vertices) i choose all of them and press the merge button. But as i do this the shading of the geometry gets

distorted and the shading doesnt look correct no more. It looks as if the vertex normals are not right anymore, there seems to be a problem with the smooothing groups of the models. You may try to illustrate this situation by making a model in 3ds max, and appliying all the faces the same smoothing. I have tried to export in other formats from max. (fbx, x, etc..) but the same problems persists. with some formats, when i import into 3ds max, i see that the mesh is not open, the vertices are welded but then again the shading of the model always seem wrong. Do I have to settle with this kind of shading if i am to close the mesh, or is there any solution to this problem? I am sending you some screenshots of the model before after pressing the merge button. (before closing (pressing the merge) the model seems correct but open, after merging closed but seems wrong)
