The more I dig into the galaxy system and the more I explore what UE5 can do for us, the closer we’re getting to a true 1:1 scale galaxy. In fact, today I tentatively binned the idea of splitting each star system into cubes and went with true 1:1 scale movement within a system. The physics seems to be handling it pretty decently so far, and that means each star system now has a scale of 946,073,047,258,080,000cm^3. That’s a whole cubic lightyear in cm, which of course by extension means we’ve actually now got the entire galaxy modelled at a resolution of 1cm. It melts my brain just thinking about it.<\/p>\n

To traverse the galaxy at that scale the ship is going to have to move at around 2,000,000 C.<\/p>\n

The galaxy itself is still split into 100ly^3 sectors, but in order to push the realism even further the number of stars generated in each sector is now being driven by a density map like this;\u00a0<\/p>\n

\"\"<\/a><\/p>\n

In fact that’s the actual density map, with each pixel representing a single 100ly sector. The stellar density currently goes from 0 to 8000 stars per-sector, driven by the 0-1 value of each pixel. The galaxy is also 10 sectors deep, so each layer will have its own density map to form the full 3D shape.<\/p>\n

So not only is the galaxy now modelled at a cm scale, it’s also the correct shape too! \"laughing\"<\/p>\n
