Well I'm happy to report that the task has been done! I successfully got a loft into TS2014. It turns out that the Blender model (still) was not facing the right direction. I also added the name of the exported model to the IGSExpModFile2, calling the file testbox_IGSExpModFile2...I'm not sure if that was needed or not but since it worked, that's will be the process for this point on.
Now...on to the night lighting!
