Weekly Update (Mar 26, 2016)

  • Traverse Team

    Hi guys,

    This week, while still tweaking and adjusting the whole space travel, we have to rework terrain system to achieve two things -- seamless landing with your rocket (no loading screens), and unlock possibility to have large terrain size (up to 20km x 20km, which would give you up to 400sq km, roughly 200sq mi of land to work with). These terrains are enormous in terms of amount of work players would have to put in to provide meaningful content for their visitors. I believe most players will choose to have much smaller planets.

    Our main objective is to create effective mechanism for both server and client to only load small area near players, and display the rest with smaller LOD (level of detail). This will improve FPS on any hardware, and reduce memory usage. In any given moment, only about 200m x 200m of terrain will actually be loaded. Full size of planet can be much larger, and our limit will be 20km x 20km. (technically this limit has to do with Unreal Engine's units being 1cm, and floating point errors that start getting quite noticeable when vertices are more than 10km away form the coordinate system origin).
