Splitting face while exporting

While I export a 3DS model, I find the following in the dump.dmp file:

Adding object state to 2 detail level(s) of mesh "Box".
Adding frame.
Object is visible.
3118 faces, 9354 verts, 9354 tverts before cropping textures and joining verts

3462 faces, 10042 verts, 10042 tverts after cropping but before joining verts
computeNormals numFrames=1 vertsPerFrame=10042 faces.size()=3462.

What is the meaning of "Splitting face (U/V coord)...."? It seems it adding more polygons to the model, how to prevent from it?

Thx!

It sounds like the texture was placed using the cropping panel in the material editor instead of using the UVunwrapper. Was this model mapped this way?

Yes... (sorry for too late reply..)
Our artist using this method.
Why is it necessary to splitting face?

Sometime the mapping is incorrect when using this mapping method.

What's happens?

Using the cropping tool to sample a section of a texture will split faces. Don't use this feature of max. Use the UV unwrapper to place your textures..
