This high detailed ship pack which can be used in any game! (But intended for RTS)
Includes:
Colonial/Pirate version
3 damage levels (transition from new to burned)
3 detail levels
1024x1024 diff/norm
To use the damage levels simply create a material for each damage level, naming it whatever you'd like. Then, in whatever script that handles ship health (attached to the ship gameobject), simply do "renderer.material=materialName;" (or create an index of materials, more on this in the docs) at different levels of health (100, 60, 20, 0) for example. The mesh of the ship does not change so do not worry about that, the holes in the sails are created with transparency, not geometry.
