So, We've built this really cool tidal wave that crashes into the side of the UN building in NYC, and in Real Flow we added a boat that gets picked up by the wave and smashed into the side of the building.

unfortunately we can't seem to get the ship's .sd files to import correctly back into LW. It calculates about 20 frames then CTDs ... any ideas? Do we have to export something specifi from LW ... motion paths?
