Hey!
I'm also experiencing the lighting issue described a few posts back. It looks like this:

I have the EE version of the game. I'm exporting from 3ds Max 2012 using the latest FBX plugins. I import with default collada settings but with cameras and lights switched off, and export with scale conversion to decimeters and lights and cameras off. All other scale settings seem to blow up the model on export.
This issue doesn't occur when I import the default body into Max and export it straight back into the game without editing. Then the lighting shows up just as it should. When I export a custom mesh this happens. The only notable difference between the two, judging by cross referencing them in notepad++, is that Max exports materials with the custom mesh. I tried deleting material data from the DAE after export but it didn't make any difference.
It'd be awesome to get a solution for this - I'm a 3D artist and I'd love to make a nice female body replacer and maybe replace some armor with new designs
