Well, I looked at the old TrueSpace forums, and based on what I found there before it stopped properly existing (do you have, by the way, any idea how much it sucks to pay hundreds of dollars for a product only to have them start giving it away for free and then closing down everything related to the program and destroying all the old versions of the software, making them virtually unobtainable, and releasing a beta version as the last version of the program they will ever release that barely works and is completely different from all previous versions? Arrgh!!!)
Anyway, looked at the forums, they said to set the scale in the info panel to 1 (which I did), and to use the Normalize Scale tool, which I also did. Every time I save the file as a .x and then reload it into the program, it is exactly 1/10th smaller than it used to be. I have to scale it up by 1000% to get it to look right in DBP.
The settings it offers you when exporting a .x file, which I just found under preferences, are:
Export geometry, triangulate all faces, store the object as a single mesh, center and normalize object, export textures and some other texture related things, some animation related things, Coordinate system (left-handed or right-handed), and float size (32 or 64 bit).
