Old update Information will be posted here:
UPDATE 02/03/21 1.7.2:
This update fixes new terrain issues around BIBF and BINF, adjusts the speed and animation of the blue whales, and adds in more objects to all coastal city ports to give them more life.
UPDATE 01/24/21 1.7.1:
This update adds blue whales and two accompanying POIs to the north of Iceland. If you stick around the POIs long enough you may see one of them put on a show! I’m going to try and add splash animations when the SDK supports them. The update also adjusts the animations of the orcas so that they are not perfectly synchronized. Check out the second screenshot for a peek.
UPDATE 01/20/21 1.7.0:
This update adds animated orcas in locations where they would be found in real life! They can be found by looking for the POI markers in north and north-west Iceland. More animals will be added and animations refined after I gauge feedback from this update. Every costal city has had objects added to bring life to the country’s ports.
UPDATE 01/12/21 1.6.2:
This update fixes some mesh conflicts from the newest update (Hverfjall crater interior and the runway at BIRE), removes redundant fixes that are no longer needed with the newest game version, and adjusted other landscape fixes to better fit with the new default mesh.
UPDATE 12/31/20 1.6.1:
