What are the model limitations?
As David Litwin says below, the maximum point count is 65k but please note the models in Bridge Commander average at 10k points. With regard to model limitations, the only one I know of is that individual meshes that comprise a model need to be less than 65k points (the point indices are unsigned shorts). But most complex models aren’t build of all one shape so this isn’t really much of a limitation. We use static levels of detail, and generally three levels for a standard ship (sometimes only two for smaller ships like shuttles, escape pods, etc.
