    • Fixed issues with roostertail physics.
    • Fixed issue where boats would slide across the water when first spawning onto the course.

    • Flags are now displayed on the HUD. This will help with awareness of penalties, start, last lap, finish, etc.

  • RE: HydroSim Sound Mod by ACER45

    It does work, you need to copy the "HydroSim_Data" folder out of the zip file and into the HydroSim folder.

    Not sure if this screenshot helps?

    I'm not sure what the problem is, can you attach a screenshot of the error?

  • RE: How do I make a dedicated server?

    The server is currently hardcoded to use port 25144 on both TCP and UDP. If you want other people to be able to connect to the server on the open internet, you will need to open the port on your firewall. If you're behind a router, which is likely, you'll need to login to the router and forward the port to your computer running the server.

    I updated the HydroSim page to mention this.

    In order for people to connect, they'll need your IP address to put into the Join input field.

    I plan on making a master server list, but haven't gotten around to it yet, hopefully soon.

  • RE: 6.1.0 download problem

    @tjz5151 I put some recommendations in here:

    That is for newer desktops, I'm not sure about laptop graphics cards or if you can even swap them out.

    If you have an older desktop, the graphics cards listed in that thread might not work for you.

  • HydroSim Alpha v0.6.2.3

    Download HydroSim



    • Fixed a bug that was adding a collider at 0,0,0 world coordinates which is in the middle of some of the courses. Hitting it would cause the boat to crash or get stuck.
    • Fixed issue with the rpm / speed readout dissapearing at certain resolutions.



    • Reverted Unity version. This should fix the crashes and server issues. I sent Unity bug reports, not sure anything will come of that.
    • Also includes the VR hotfix.

    • This fixes a bug when using VR mode that would make it so you couldn't re-join the course.

    @Andrew-Waring I've had issues where sometimes the wheel doesn't get picked up, but if I power cycle the wheel, and restart the game, then its fine.

  • RE: Hello

    Not sure why the Fanatec wheel wouldn't be working, as far as I know it uses DirectInput like everything else.
    I'm using a Fanatec Forza CSR wheel and ClubSport pedals.
