Baking a Bitmap in 3DS MAX Across Multiple Contiguous Objects

[SandorWren]

The house Caitlin and I have is made up of multiple linked sections.  Floors and walls have multiple sections. The textures line up correctly to appear continuous. They are "baked", since lighting and shadows are a part of the textures. I can do this to a point, where my texture is broken up into individual bitmaps matching each section of a plane that I detached into 4 objects (using render to texture). The problem I run into, is when I upload the mesh object, and apply the textures, the UV's aren't correct, and the textures are enlarged. Fiddling with the scaling settings in SL doesn't help. Can anyone tell me how to do this correctly? Should I be using Udim tiles?
