boat building station optimisation
its 7 buoys were embedded pre-merge copies of the ocean wreck buoy optimisation i did on changeset
162514 - replaced their 280 seaweed/mussel renderers with the buoy merge's existing combined meshes
combined the remaining seaweed clumps in the station and platform prefabs (6 -> 1 and 5 -> 1) with wind origins baked into UV2
none of the seaweed was ever batching at runtime
renderers 340 -> 65, prefab 1.4mb -> 296kb, seaweed is now 9 draw calls instead of 263!
