Exporting from 3Ds texture map issue

So I went with my initial hunch and tried a different approach to UV mapping. I added 2x UVWUnwrapping modifiers and unwrapped the textures on the channel 1 map, and then unwrapped my lightmap on channel 2 instead of adding a UVWmap on channel 1 and a UVWunwrap on channel 2 - and VIOLA! It’s working!!
For some reason the UVWmap was messing up the textures… I have no idea why because all my other meshes use this mapping modifier and I don’t have problems. And every tutorial I’ve watched uses a UVWmap modifier. So I’ve found a work around but maybe someone can chime in here so I can understand whats going on aswell as anyone else with the same problem in the future…
