Across the Seas - Maritime Simulator Unreal Engine based Version

[MarkoBarthel]

Ahoi Captains,

 

Across the Seas is not dead. After an long time without any news about the sim and it's current state, I'm back with good news. 

After the first internal test version in UE 5 with an mostly off Blueprints based version, I wasn't very happy with the result and the state of AtS. So I decided to take an fundamental step and so I started from scratch with UE and a C++ core code of the sim. So after getting a lot of headaches and  pain, now the physics and the watercraft controller are full written in C++. Also the base of the GUI is completely C++ code.

Across the Seas will now be developed in UE 5.8. This version brings a lot of improvements like a good implementation of 64bit floating point precision (with Unreal's Large World Coordinates) and mesh terrains and other UE features like Metahuman, Metasound and Megalights. 

 

I'm quite happy now with the way the simulator looks and feel. Most parts of the water and weather systems are done. With the further development of the sim, I will also make improvements and adding more features to the watercraft / player controller and also to improve the GUI.

So the release of the first UE based prototyp, I have decided to give it a go at the late Q3 or early Q4 of 2026 release. Like the old Unity version, I will update the alpha/beta version during the development period. Here is also an Trello Board with the status of the sim.

 

Main features of the Unreal Engine version:

- C++ code base for physics, watercraft controller and the GUI

- Support for very large sceneries

- Native DLSS 4.5 and Nvidia's Frame Gen integration (FSR integration Work in Progress)

 

Stay tuned for more news and the first new version of Across the Seas.

Regards
Marko
