Jim, would you explain this? I'm using Modo and Silo, mostly. So, this might be a problem. Nevertheless, you can pretend I have XSI in your explanation, if you have time.
"I know I can take a camera mesh export of a terrain from TG and put it in (for example) XSI, and then position an object in there far more easily than in TG2. I then export the object for importing into TG2."
