How do the damaged models work?
David Litwin explains… Damage volumes are added when a photon or phaser hits your ship. If you have visible damage on, we have a voxelized version of the ship and the damage volumes are intersected with that to determine where the damage has been done to your ship. Your ship has differing thresholds of when it scorches, when it has skin damage and when it has internal damage. Based on these values some damage may blacken your hull, may cut a hole in and and girders of the skin of your ship will extend over that damage to varying degrees.
