Homeworld 2 engine doesn't use bumpmaps, so Warlords models don't have bump-maps. However, for EaW/FoC's engine to compare with HW2's, it needs it's one advantage: bump-map capability. Bump maps actually look better in EaW than modeled on details (due to the engine's lighting effects). Unless a model is in the multi-100k range of polies (such as the original Legacy SD model on scifi meshes), textures tend to look flat even with modeled details. Bump-maps give a 3d effect without having to model (significantly increasing poly count) all the tiny details of the texturing. But I digress. Use em or not, your choice. I'm just saying they'll look better if they get added. Either way, imagine high-polies...with bump maps. ;D Very good eye candy, lol.
