Can you please explain it, like you would explain it to a baby that is 5 years old? Because I couldn’t follow you…
First of all what I need the scale for or the vertices?
As a newbie like me thinks it: I just want a real big terrain same as skyrim’s, how can this be? By adjusting XY scale to larger values I can achieve this. This the result or the outcome if you’d like that has come out of this thread for me…
Okay
what for software are you using? that i need to know
I am using world machine
Okay
First build in a reseltion of 4033
then you need to do some calculation 40KM i would sugest of 20 40 wont work the sky box will interfear with it so keep it 20KM.
so 20,000M / 4033 * 100 = 495.908 that is your XY Scale For 20KM. now your hight tell me that then i will do the calculation.
remeber that formula. https://docs.unrealengine/latest/INT/Engine/Landscape/TechnicalGuide/ . there you will find the reseluiohn you sould build on. send me a private message i can sow you more.
Pmed you, but I really can’t underestand the usage of this formula on the unreal wiki. It means that if I build in world machine (or the editor??) in 2k resolution I must manually make the changes in the components,quads,etc in the editor?
Okay
So firts learn world machine and UE4 a bitt better so hear are some links.

After that make a awsome landscape than read this some more.

this you can also do

I hope this helps first learn ue4 and world machine a bit more.
first learn to walk before you can run.
Thanks, I’ll check the links
But for real, can anyone just tell me a guess of how much resolution and how many km’s skyrim world is? One who would like to build such a landscape, on what resolution should we set it up to and how much XY scaling?
Regarding to the opinion from the epic devs, it’s around 5x5km – so as big as the landscape mountain demo map -> I’m not sure, but the heightmap in the landscape demo is around 2048x2048 (just download the package and check it) 
(14:14)
5x5km and I’m talking about making a 20 x 20 km? Oo When I make a 5x5 km it looks so darn small…
Even when you use the character view + when you add some meshes? 
With a good level design you can give a feeling of a large world to the player -> e.g in skyrim there are many mountains. So even on a pretty small area it takes a while till you reach a point, because you have to walk through small valleys, you have to climb up a hill,…
I will try to add some foliage and some meshes there and see how it will turn out
Btw to be sure, to make a 5x5km I must build on world machine(and editor) on 505 x 505 resolution?
Oh wow checking my spelling yea i can see why no one could follow me.
Okay let me explane it again. So let tell how i do my workflow. First i make a landscape in world Machine. The Size is a inportend value. So lets make it 8KM - 8KM, something easy.
Now when we build a lanscape on a resolution 4033 x 4033, we have to do some calulations. When we inport this landscape without doing this we get a problem that the landscape is too small. So we need to scale it up for that there is a calculation. Just so you understand a bit more, if we now inport we get a landscape of 4 by 4KM big. Thence the 4033. Since we are going to work in Meters lets first convert everything. 8KM = 8000M simple. So now here is the calculation 8000 Meters (The Landscape size(This value you can make anything)) / 4033 (Landscape buildsize) * 100 (There was a reason this was here but i forgot) = 495.908 This value is used in your scale of the landscape when inporting. So in your X and Y You put in 495.908. Now you have a 8KM landscape. Now if it looks like your hight is not matching with World Machine. That can be since you also need to edit the Z Scale That is simpler. In world mashine in the world settings you see the setting for General setup. There you can ajust your overall height. Take that value and calculate it like this. Lets say its 4800 So 4800 * 0.1953125(Why this i dont know but its the majic number) = 937.5 That is you Z Scale your need so the Height look good. I hope now it was better?
