Michael - Thanks for taking a look. These objects were never created as instances. They were merely copied and then transformed individually. This may be an issue on FormZ's end as they just brought back clones in V8.6. I'll bring it up on their forum and see if I can find a solution. In the meantime, I am getting good results using SAT version 10.0. Thanks again for your help. I still can't believe how beautifully MoI exports out to OBJ. I could never get anywhere near these results using FormZ. Kevin
