Importing Real World Heightmaps into Unreal Engine
Вставка

- I've been looking for a way to import real world heightmaps into Unreal Engine, but have found a lot of UA-cam videos that don't cover an up to date or free version to import this amount of real world data into Unreal Engine. There is also terrain party, but it's a bit low resolution to download from and is isn't always available. This is the solution that I've been using for a while and I'm happy to finally share how to do this with Unreal Engine.
Resources:
The website you use to get the heightmap data:

Like I said, this man honestly has done so much work for UE in the past and the fact that he's offering such a fully featured app for free is amazing. I'm not even payed to say that, it's just an amazing program considering the pricing of other options.

Feel free to explore them, there are a lot of underrated Unreal Engine UA-camrs. Unity is taking up all the spotlight :P.
For anyone being scared, don't worry. I'll release videos again after the weekend. Just hold in there ;-).
Great tutorial. Finally one that doesn't let me follow along for 30 minutes and than casually mentions, oh yeah you need the professional version of this tool which costs thousands of dollars to proceed. Thanks, this really helped.
lol this has cost so many times before. spend 10 hours collecting data and then find out you need to convert it in a paid software or something
Amen!
@@Kevinbaconator_ That is why I 'll never try again. Now I try to make games without landscapes
Explained so clearly. ! Thumbs up, and subscribed (all videos)
Really great tutorial thank you ! Gonna try this later when I get home
Thanks so much for this tutorial! I was wondering if you could do a follow up that includes some additional visual data. I'd like to bring in satellite and OSM imagery, and use it as reference to recreate landscapes within UE.
Outstanding work. Thank you so so much
ty so much man, i will try it right now! all other tutorials i watched did not work with my desired map :'D
Is there a way to combine several heightmap files into a larger area file? or is the current process to import them one by one, and line up in UE?
Yes
You are underrated fr g
Thanks for sharing.
You're a hero!!
Couple of questions-
1) As you can see at 1:40, it seems that the aspect ratio of the SRTM tile show in the map (greyscale rectangle) is something like 2:3 but it is exported (bil, tiff, etc) as a square. Why is this and does the exported file need to be adjusted to compensate?
2) When I import the SRTM file (.bil) into TerreSculptor, the height is completely off. The elevation is much too extreme. Do you know why this is? Thanks!
Hey did you ever find a fix for this issue?
How can i optimize the terrain for a first person shooter? There must be better ways intead of sclupting the whole map for great details.
I'm new to unreal engine, but if I realize I've screwed up after pressing import is there no way to edit or delete the environment that was created?
How would you blend 2 of these height maps together? I have a very particular part of the world I'd like to do this to but the feature I want to build around is split in half on 2 files.
i need to blend like 30 for my game lmfao if you ever find out PLEASE tell me
@loganfrancel9275 I'm using ErrantWorlds landscape plugin and you can turn features into brushes and have pretty performant large landscapes with it. You can feather out edges and prioritize brushes that overlap in a layered approach
How do you do this if you want to load in say a whole state vs just a small section?
Great Nick Name i thinked on "Keyboard Not Found, press any key to continue" lol Useful video Buddy thank you
Can you make and updated one for UE 5.1 and show how to place multiple tiles from USGS and TerreSculptor, thanks.
"The provided maps are not for purchase or download; it is to be used as a guide for reference and search purposes only" Download option is greyed out. Is there a way around this?
create a USGS account
Could you show us a way to efficiently import a height map of the entire world? It seems like downloading it from USGS that way would take an extreme amount of time.
how can I connect 2 terrains, so that are perfect aligned on the sides, otherwise I have to sculpt all the sides of the terrain
This is a good tutorial bra!
Hi, I wondering if you can make a video explaining how to use height res data using the new World Partition System in UE5?
Sure, the system is way simpler than world composition in UE4. Stay tuned for that video.
@@InsertNameHereGameDev yea I tried ue5 tonight and it went totally wonky on my will see if you have your video or keep an eye out for it
What if you try to do this with a piece of landscape with Buildings on it?
hi, im trying to do the math for the scaling inside UE but, lol i have no idea what the original resolution was lol
I don't understand the formula, though. The map I downloaded was 8129, so...
Hey so terrasculptor is this free anymore. Do you know of another method that does that require a lot of money?
your brilliant
Where does the 3601 ratio come from?
... Do you need to have an account to download from Earth Explorer? all the download buttons are greyed out for me.
When I import into TerreSculptor the terrain is skewed, seems to be multiplying the Z axis a lot so it's very tall and spiky. It seems to be different to use terrain map from outside the US. (I'm trying to use somewhere in Scottish Highlands) I went into Modify > Altitude and shrunk the min/max values to get something, but it was pure eyeball work
having this same issue.. the bil file is rectangular but when imported is shrunk one direction into a square which skews the whole heightmap
Did you all ever find a fix for this?
@@merited8379 Not really. Outside the US the maps tend to have lower resolution, so you need to stretch the map out so it gets flatter, then you're left with what looks like a tomb raider 2 landscape, so manually go over it with the smoothing tool in UE editor. By the end of it I was basically just hand crafting a map anyway :) There's probably higher resolution maps for your region if you know where to look, but I got the result I wanted so I didn't do any more searching.
@@phraggers Noted. Thanks for the reply!
how can you change the setting to be 1 arc instead of 3 arc
After I scaled up the landscape with the same settings as in the video, I find myself unable to get close to the landscape without it disapearing. I am in UE5 and trying to make this work with world partition. Any suggestions?
same
@@BushdoctorsLab I did find the solution, in world settings search up the "enable large worlds" option and check that, works like a charm. Good luck to you.
Would this work for unity??
it won't download for me, in the results section. how come?
how to know the original size of the terrain
?
Hi! I am geographer and I wander if I can and how to georeference my SRTM or DEM in UE5?
Ugh Terresculptor is not free anymore! is there any other way to turn the heightmap into a PNG without spending money?
You can use goggle map transport into unreal 5
@@user-mn2vb6rd5f no you can’t. Google maps does bot have height map Information
TerreSculptor 2.0 is free
Is there a way to also download the satellite color image?
Sentinel-2 or one of the NASA Visible Band Maps (google the name) should be in the same webpage he got his height map from. Look for it in the dataset section
FYI for new users "The UDK Button has now been renamed to the UE button. You can enable it by going to the Settings, Dimensions, and enabling the Unreal Engine item."
the program isnt free anymore
@@therealbstreets version 2 is free, version 3 is not.
@@airmanparker I didn’t see where to download anything free on the site
@@therealbstreetsGo to the support page, 2.0 is there.
under the support tab @@therealbstreets
So I tried this usgs tool for extracting data from my home town, but there're no results. It's outside of the US if that helps
do you live in iceland or one of the far northern regions?
You said free software but when i hit the link to download the Terrasculptor, it's cost 99$. Is there any free version?
yes
if you go to the purchase page and read the description, there is a link to download terrasculpter 2.0 for free from the archives page. here is the link www.demenzunmedia.com/home/support-archive/
Login required at the usgs page
how big of a map can terrasculptor make? like I want to do a 20km x20km open world map can i map. can I make a map that size in TS? then tile it
The maximum sizes supported in the software can be found on the TerreSculptor Features page: www.demenzunmedia.com/home/tsfeatures/
The editor can currently create heightmaps up to 46k x 46k with a BigArray Update coming soon to increase that to 2 Billion x 2 Billion.
And the Tile Creator is currently limited to 23k x 23k but the next build will be 32k x 32k for 16-bit heightmaps.
A new Heightmap Split tool is also under development that works up to the full heightmap size of the editor.
@@daveg4417 thanks yep im still playing round. will go back to importing in 4.27 and see if I can get them adjusted as it came in at a weird scale. I did as the video here said for choosing the 4033 but it didnt come in like that it came in as a rectangle in UE5
@@proflooney - Ok. I have yet to do much in UE5, I'm currently swamped with work and still getting past the UE4 video tutorials and such.
Doesn't work anymore. Website request login and a lot of personal data to create account
it works! And it's a US Government page lol
it will not let me rescale the landscape it in the landscape creation tools. When i type 28,7865*100 and hit enter, it just resets back to 100 like i did nothing
I think he is using a comma in place of a decimal point. If you try 28.7865*100 instead it does take the formula. The problem I am having is at that scaling it still does not look right.
Really disappointed that I can’t find terrasculptor 2.0 anywhere.. how can a software just disappear off the face of earth? The new terra 3.0 is $75
Go to support, then to the support archive. You can find 2.0 there, I just did it!
@@bigsky7617 thank you. I was so frustrated🤣
@@Instant_Nerf you bet! I was too, especially since every other video tells you about 10 minutes in that you need some premium software 😡
Do you have a email? I would like to pay you to do me a service
I'm not even going to try, I've spent too much time trying already, with no success
i do not see udk landscape but see unreal engine
Same thing, far as I can tell. Just updated.
There have been changes since you made this video. 1) They require that you have an account and be logged in to download data. I tried to register but ended up in an endless loop. 2) The second program is no longer free to use. You must pay $85 for the program in order to use.
1. It has always required a account (I might not have really pointed that out well, this was one of my first videos...).
2. That is actually true for version 3 of the program, but version 2 used in the video is free. Here is a link to that (this is an official drive link from the website):
drive.google.com/drive/folders/1ymTqvO2iavh-eWFk7LZorXcbuyP0S3Fb
3. But yeah, this video definitely needs a redo. I've grown my channel quality and Unreal knowledge a lot over this time. :-)
The software is no longer free :(
its just hidden on their site under support
@@optimuspr1mate762 Thanks, I used qGIS to open the tiff and convrted it to PNG. That worked well too..
Fix you’re description.. it’s not free it’s $75
If you go to the support tab, then down to support archive, you can find 2.0 for free
lol now you have to fix your comment haha
