Hello I need to figure out a way to make a map that represents a 10000 x 15000km map in a seamless fashion. So far without proper success I have tried loading the whole map as on terrain… worked OK and i could fly around it but that was while it was empty. The next thing I tried was world composition in various forms and sizes. These worked for the most part but due to the size of the map and in an effort to make smaller levels players would be on before moving to a nearby one i ended up slicing it up into 4096 levels but was unable to import all these maps at one time requiring me to import roughly 123 at a time and then they didn’t line up right. So to experiment i took the same map and only loaded in around 30 tiles covering a map roughly 60km2. This loaded in fine but I then encountered several issues. 1. the map was cut off by the orange world borders thingy. 2. as i moved around the map did not re-center to the player so that they stayed in the middle of the orange box. 3. light mass volume whatchamacallit wouldn’t compile and spit out massive errors.
Things I have considered. Scaling the world so everyone and everything is a fraction of thier real size so the world would be like micro-machines… scale the world down by like 1000x and scale all buildings, trees, players, cameras etc by 1000x so to a player it is still just as large but in data it is all much smaller… however I haven’t quite figured out how to do this going from world machine to UE4 since I need to maintain the world machine’s quality so i don’t have huge cliffs where a slight hill should be.
I have also considered some method of multiple side by side world compositions but no idea if this is even possible.
Please provide any all answers you can especially if the epic games could chime in here. the more details the better. Thank you.
A secondary question is when importing the height maps following world composition guides for world machine i ended up with 4096 height maps but when i try to import them UE4 uses the windows explorer file opener rather than a custom opener and as I am selecting multiple files i can reach around 120 or so selected files showing in the open file box as “file1” “file 2” “file3” etc but after a certain unchanging number the box goes blank. I can still select the files but they will only select visually and the box will remain blank preventing import. I confirmed this was something with windows not UE4 as selecting the same number of files in notepad++ does the same thing. However speaking to others who have use UE4 and people in general using notepad++ do not run into this issue and appear to be able to select as many as they want without issue.
