This model is certainly way too high poly to really consider using in game, and not necessarily because of the overall polycount,
Hi brand, thanks for the input, but I have to admit, I don't really understand the quoted statement above.
A few caveats, whether my model gets used in the game or not is totally up to you guys, it won't hurt my feelings if you decide not too.
From the start I've modeled the Naboo as a learning excercise for myself, if one of the things we learn is we can't use NURBS then I guess we learned something.
Currently the model's detail0 polycount is around 5700, which is about 15% more polygons you would want for a standard model, but then again this isn't a standard model. It has changing radii in both dimensions, NURBs as a modeling technique is probably the most accurate way to capture the shape. Once you have the NURBs form you have the option of how many polygons to use when exported. You can make it as course or as finely detailed as you want.
I plan on developing it all the way and getting it in game. Once I have walked through the entire process, I'll have a better idea how to refine it for the next ship.
