This model was created in Truespace, triangulated, and exported using a TSX based PSK model exporter. I attached the TSX plugin to this post for anyone who wants to convert TS created models to the UDK PSK model format.
The original Tank model was created for BZII Combat Commander; it's a low poly version optimized for BZII. The PSK model format apparently supports animation and may be of some use for project Genesis. Low poly models can be converted to higher poly models in TS through sub-division modeling tools available in TS.
