Back in Homeworld 2 like 4-5 years ago now, when Black Sun was first being built as a mod, I used a slightly kitbashed Hiigaran BC someone (I think Axel) had made publicly available. It was used for an Anahn corvette called the Raptor.
I have ripped that model out of HW2, refurbished it, and given it new weapons.
I've kept it rather simple since it would be a small ship, but it would make use of four weapon types - Rapid-Action Burst Railcannons, Battlecannons, Quad Powerguns, and nuke torpedoes. The smoothing needs a bit of work though. The model, when it came out of the HW2 format, was a colossal mess. Might add some more turrets.
