Hello everyone, I was trying to make a lowmid poly count model of a USS Keokuk class ironclad, but realized that at this point, I’m really not sure on a good way to go about creating the smooth sloped armor on the ship’s hull.
What I’ve tried so far:

I’ve tried taking a ‘spin’ approach, using the spine from the mid hull to the upper hull, rotating from a pivot vertices until the far end lines up with the verts on the mid hull. Of course the problem is that since the hull is not uniform in shape, the spine gets further and further away from the ship as it gets spun, meaning that I would have to smooth the verts (which I tried but it really lacked accuracy).

I’ve considered making a polygon for the top of the hull (on which the turrets sit) which would establish the top, but then I’m back in the same situation as idea 1, where I have to create the slope by hand.

take the loop from the mid hull, duplicate it, move it up, scale it in. Might be okay, but concerned about ‘lining things up’ when it meets the upper deck shape since they are not identical.
I’m just looking for some general advice or direction to go, any ideas are appreciated. Thank you for reading.
