Again, this is a good place to mention the free Poseray program. I think it's a great companion program for TG2.
One feature I like is the materials tools. After loading your model, may get a warning about missing maps. This is normal if you store the image maps in a different folder from where the object is located.
So now you can click on the Materials tab and get a list of all the models named surfaces. There's a button labled "Tools..." and one of the options is "Find all missing maps." Selecting that option gives you a Map Search dialog where you can add paths to where your images are stored. Then, clicking "Find" should result in a "0 warnings" if everything is found.
The "Groups" tab lets you recalculate normals, remove orphaned vertices, etc. Many options here that can come in handy.
Then there's the OBJ output tab where you actually set up the export of your model to your TG2 scene folder. One option is "fix material and group names." Click on "Export..." and there you can choose the option "Copy all maps to the same directory." I usually choose this because I think it simplifies things -- you have all your TG2 scene files, including object and maps, in one folder. There's also an option to "Fix map max resolution to xxx". If you wish to keep the largest maps to the original size, set this value to the largest size. The aspect is maintained and no smaller maps are resized (to the value you entered.) The maps are stored as jpg.
There's also a POV-Ray Output tab which I've found to be handy to get a quick render of what you've loaded and set up in Poseray. It's much better seeing obvious problems with your model in a quick POV render than a long TG2 render. Of course you need to have the free POV-Ray renderer installed. Once you set the path to POV in Poseray, you can then do a "Save and render..."
Anyway, I think Poseray is a great way to prepare models for TG2.
