I would make sure that you do not have issues with backfaces. Backfaces come into Lumion transparent with no material, which sounds like your issue. Make sure all polygon faces are front-side material. You can test this by creating a cube, adding texture to all faces and reversing two faces, add texture to the reversed faces, and import into Lumion. You will not see the reversed faces, they will look transparent...and if you go into the cube you will see the two reversed faces and not any of the others. Hope this helps.
