cautious consideration. What about ships such that have portside and starboard mounted heavies? Wouldn't the lack of a 90° vertical firing capability be a huge hinder?
These new models are tuned to 45° because that's the vertical arc on the current Mortar and HMortar's models, so their performance ingame is gonna remain the exact same.
FL engine adds some leeway to the firing arc (roughly 35-40° from each side, both horizontal and vertical) past the model's actual rotation limit, which is why it may seem like some turrets rotate more than 45°. That arc is not part of the model's "physical" rotation limit, and if you look at them closely, you'll notice the actual model of the weapon never rotates beyond the 45° point vertically (with only a few exceptions, like battlerazors). In fact, almost all snub guns and hardpoints are set to -45 45 horizontally and 0 45 veritcally, but they can cover close to a 180° cone in turret view just because of this leeway.
