@OrbWeaver Your solution 100% worked, I'd forgotten to include smoothing in the LWO export. Thanks to both you and @HMart for the help, next step will be getting it set up as an entity, then starting on more models!
[Edit] So, a few questions. First, does TDM support ambient occlusion maps? Second, are there any A to Z-style tutorials for Blender->TDM modeling? If not, would it be useful for me to try putting one together?
