Ok, I put it in-game and here are some mistakes to learn from them -Origin point was under the waterplane (below origin coords). Looks like the deck is full of water: -The props were parented to "box012" and "Mesh" empties (there should be parented to the actual mesh named "untitled") maybe it's caused by the exporter, I don't really know. -The ship was not centered at origin coords (0,0,0) so the ship turned from a wrong pivot point. -It was facing the wrong direction (just rotating the whole ship 90ยบ before exporting fixes this) I fixed this issues and here's the final result: I added the fishing ships to compare scale. The model looks great, but maybe the whole ship needs to be scaled up, but I don't know how big the actual ships were. And we're going to need playercolor on the sails definitely, what do you think?
