I wanted to ask about the recent increase of map sizes to 20km. Normally, when using Single FP, there’ll be precision errors after a certain distance from the origin is reached.
That’s why the World Composition feature is in, it shifts the origin so that you never have too “big numbers”, where precision errors could come up. Another possibility would be to use doubles instead of singles, but that would decrease perfomance and increase memory consumption generally, which is not ideal, because not every UE4 game needs big maps.
Now my question is, how do big maps hold up in terms of precision as of the 4.6 update? Also, what has changed technically to make 20km maps now feasible?
If this question has been answered before, I’d be happy to be given a link. I’ve searched before but couldn’t find a suitable one.
