Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

What is the formula for finding out the square kilometers or miles based of the terrain size and Unreal units.

What is the formula for finding out the square kilometers or miles based of the terrain size and Unreal units.

For instance a terrain of 4096x 4096 would be how many square miles or kilometer using the Unreal unit of measurements ..

Also I've read two different unit measurements one says it's 1UU = 1 CM the other says 16UU =1M.

It would be nice to have that displayed when creating creating the map. I know once you have created it you can adjust the size and it would be great to see that as well when you make the changes.

The great thing about L3dT is it tells you the size in kilometers based on the terrain size and scale.

You can change uu <-> meters scale in WorldSettings (though I strongly advice you not doing that, it is uncommon configuration and has high chances of hitting exotic bugs). By default, 1 uu == 1cm.

I know you can change the UU but that's not the main question. So how does the 1 UU= 1cm translate to the square miles or Kilometers of any given size terrain ( 1024,2048.4096 and so on) There must be a way to calculate the area. The question is I guess what is the terrain resolution measurement scale in relation to the UU scale ?

If the scale is 1UU =1cm then how many square mile or kilometer would a 1024 x 1024 terrain be. I would think there would be a way to figures this out even if not exact..

Hey, did you ever figure out a way to calculate the size of terrain in m/km?

Old thread , yes, but it may help someone . The answer is, 4096 is in meters . Divide 4096/1760 ( since a yard compared to meter .91,,close enough ) . You can get to Km by using online guide: convert miles to Km .

What I need to know, is how to figure HEIGHT of terrain as I've found nothing atm to do so. There was a website but I can't find it anymore. I kjnow the height' scale in UE4 is 150, while x & y are both .73, but I've no idea how they interrelate to each other ;)

Anyway there is your answer ;)
