This program is amazing, but I seem to be having trouble importing my json of the city I made on the city generator. Whenever I try, it says "No buildings!" and returns to the sample city. Any ideas on how I can fix this?
This is not a city generator, this is a city viewer! It comes with 6 built-in settlements, but to see something new you'll need to generate a city in MFCG (or a village in VG), export it as JSON and import it here.
Right-click anywhere on the generator to access the context menu with all the actions and options.
- Enter: load another built-in city.
- 1, 2, 3: switch to one of 3 viewing modes
- 5, 6, 7, 8, 9, 0: switch to one of 6 colour and lighting modes (styles)
- G: toggle gable roofs
- X: export the model to .obj
- ~: toggle auto-rotation
- Shift+1: switch to the fly-through mode
- Shift+0: switch to a random colour and lighting mode (style)
Use W, A, S, D and arrow keys to navigate around.

Are you sure you are importing the right json? I mean not some palette json or something like that? Could you send me the file so I could check it? Or maybe just paste it here if it's small enough?
I thought I was doing it right- here's the file. https://drive.google.com/file/d/1-LS-mMnuAqgBuXCz6BQk8bXt8gZgItq8/view?usp=shari...
Nope, it's not a city json. It's an ImageMagick's json ("version": "ImageMagick 7.0.10-58..."), something like a description of an image (a city map I guess) with its dimensions and other stats.
I'm currently on this WIP: (render result) & more recent version (2+ days) [HERE] (For some reason i the second ver tha grass got some horrible coastline bugs) and wdytai?, it's pretty hard to put those lights in the houses, soon i'm planning to put some light source windows there and textures, even if i still haven't managed to get them right ever xDDD
It's a great program, it's very pleasing in my opinion to make towns and this makes it a lot easier, thanks xD
Very cool! That's how I hope to make it look right in the City Viewer in some very distant future. I'm talking about the first render, because there is no chance I'll be able to implement as many details as on the second one :)
Recently there were a couple of requests for OBJ export with materials. I'm planning to implement it in the next update and hopefully it will make working with exported models easier.
yeah, i know what you mean there, also it would be impossible to put grass on obj, as it makes many pc’s (mine included) to go to it’s very limit xD
also i know that making the materials for this is hard, let alone puting materials in surfaces on blender is enough”ly” hard, i can’t come to imagine how hard will it be to implement material adding on haxe.
still you are the best, you actually make it easy, not like probableTrain, that made a good algorithm, but ruined it needing to add bools on stl files, wich is extremely conflictive
Is there anyway to export the colours along with the OBJ?
I love export option! In fact i even did this render of city i exported, althought i have found some small issues model.
1) City wall exits have faces that are clip through each other
2) Walls also can be cliped inside themselves sometimes, it is pretty annoying
3) There are long random triangles where the roads shoud be, but it is very rare, i had this glitch only once
Anyway, here is my render of cardboard city generated with your wonderful tool
First of all, this render of yours is VERY cool! Can I share it on my Twitter (with credits of course)?
About those issues - that's how the viewer works. I don't have many tools for procedural mesh generation (in Away3D), so, for example, a gatehouse is just three boxes combined without trying to clip anything. I probably can (and should) fixes gatehouses, but walls are harder. If you take a look at exported mansions you'll know it can be much worse :)
Thanks! Yes you can share my render. If gatehouses made out of three cuboids I think it can be fixed by moving top of the cuboids down.
Everybody likes it: https://twitter.com/watawatabou/status/1390042322855989251 :)
On my next iteration I'll remake gatehouses properly. This 3-boxes thing is copied from Toy Town. It was more or less my first 3D app ever, I can do a bit better now.
So for all People Going crazy and having a Problem with the Normals, Export the Obj. to Blender, Go into Edit Mode, Press 1 for Vert, then Press F3 Type "Merge by Distance" then do a Merge by Distance and Shift N to recalculate the Normals should be Fine then.
So I made an fbx out of one of my cities I created and passed it to unreal and unity and when they come out they appear concave and completely broken? I am kinda new to all this rotin tottin exportin and wanted to know what am I doing wrong how could I fix it?
- I know nothing about Unreal.
- I know roughly the same amount of nothing about Unity, but at least I have it installed. Indeed, it looks like all the normals are wrong (flipped). Probably Unity expects a different vertex order or axes are supposed to be oriented differently? Anyway, you'll need to flip the normals of your model, but I have no idea how to do it in Unity.
I'd love to have the option to load predefined textures. Grass, sand, water, fields, rock/brick walls...
Apologies if I am being stupid but when I import my city into the viewer it only displays the castle/temple - every other building is missing. Is there a setting I need to tweak or is this done by design?
Cheers and gratz on the great work.
That's weird. This is the second report on this issue, but I can't reproduce it. Could you send me your json file?
Happy to but where shall I send it? :-)
I've found what causes this problem and it will be fixed in the next update. Until then, you can make the export work by choosing any value in Style > Buildings > Shape (Block/Off/Simple/Complex).
Thank you that was quick work :-)
Hey, I'm also having issues loading my Really Big Map, but there's no such thing as a "shape" menu in the Buildings section. It doesn't exist?
It does, it just is not labeled. The last item on the Buildings tab, a "combo box" with values "Block", "Off", "Simple" and "Complex".
Hi there watabou, great generators and viewers.
however I am having the same issue as jsunandmax - I took the Json from MFCG and imported it here, exported the obj and opened it in blender so I could scale it, I then took it to table top simulator.
once in TTS I noticed the normals were crazy - most of them appearing inside out, but some flipped outside.
I hopped back into blender and there was no fast or easy fix I could work out to sort the normals.
I think this is happening because the meshes are @open@ the buildings have a roof, and walls, but no "floor" or base. would it be possible for you to have an option to make the meshes "solid" as then even if the normals are from some reason inverted, blender can recalculate them to be "outside". at the moment since the mesh is "open" it cannot figure out inside from outside and just flips some one way or another.
great work! I noticed when exporting .obj and bring into Blender that normals are all crazy (random), and since the bottoms of buildings are "open", its impossible to get all the normals facing right. Is this something there is a solution for?
Are you sure the normals are incorrect? In City Viewer models are exported without normals so they should be derived from vertices coordinates in the obvious way by an importing application and I don't see what can go wrong there.
i figured out the issue, .json from the Fantasy Village to here then .obj out creates geo where vertices are not welded. Once I did a weld, i could fix all the normals, even without a proper "floor" on the buildings.
Hey! I really love this - especially with the ability to load jsons, but there's a feature in toy town to set it to a "45° orthogonal view (RTS view)". I used this generate 3d maps for my players - is there a way to implement that here? Thanks!
Yeah, sure, it's on my list 👍
Any chance of making a variant of default view that allows for no animation? I'd really like to be able to use this tool to figure out city shots for ex. a comic (or other sequential graphic arts) but locking camera to ground and making the motion quite slow in that mode doesn't allow for the range of poses needed.
WASD/arrows for XY camera motion and mouse to rotate camera work well enough, perhaps the zoom wheel for Z-axis or FOV (and if using it for FOV, R/F keys for Z axis?) (I am not a patron so take this all with a grain of salt, ofc.)
EDIT: I am an idiot, space-bar unlocks Z axis control...... gosh, what a cool tool
Yes, the SPACE key unlocks Z axis (it is locked initially to simulate walking). You can also use numpad + and - keys to adjust height directly.
Slow walking is a problem. Usually when I need to take a screenshot I use the "Default view" first to get to the right part of a map and then press ~ to switch to the free mode.
When I hit export all it does is regenerate the city and I don't get the file?
I'm running a windows machine and I exported a JSON from your other thing to make a non-prefab city.
Is there a way to see what's going wrong?
Sounds like a keyboard issue (layout, caps lock or smth like that). Do the other hot keys work normally for you?
Ditto with these two.. any way to make it work locally, when internet is not available?
This is even more stunning. Needs trees, tho. ;)
OK this is well cool. I'm not particularly technical but is there a way to turn an existing city into something that works, i.e. how to convert a graphics file into JSON?
this is super nice but could you add a option to export the ground plane?
Ey, any chance of a downloadable version? The in browser one takes a long time to load ;-;
Can the cities made with the generator be applied to a unity terrain, or Gaia
Only if you (or someone else) will write code parsing json produced by the generator. It shouldn't be hard, but it's just my guess, I personally have zero experience with Unity.
This is great tool. Maybe I use this tool for Unity. Thank you.
Awesome tool for visualizing the generated cities and villages!
The OBJ conversion is a real kicker too, and it helps me visualize what the village actually looks like!
I just noticed that the generated OBJ file is upside-down compared to the map and the view generated in City Viewer. As a consequence the OBJ matches the map only when viewed from below :-)
Thank you for sharing great tools!
i would love it if there was a scale so i could see how big everything is. amazing tool other wise
I can't seem to drag and drop the .json into the viewer. I'm using Linux (Debian derivative), would that be a problem?
I have no idea (virtually zero experience with Linux), sorry. Since a standard browser API is used, in theory it should as good on Linux as on Windows or macOS . How does it look? You drop a file into the viewer and nothing happens?
Sorry about the late reply. Yeah, the mouse over with the dragged item does not even change to show it is droppable there. It does however, drop outside the viewer in the same webpage, but then that only makes it so that the viewer's webpage goes to the code contained in the file (a la, using a browser to open that file's code/script). Very weird.
I downloaded a new example and it looks like it works, see the README on github, I put an image. There is no city walls or water body yet (because I didn't need it) but if anyone is interested in it, I can implement it. I think being able to re-color every building is pretty neat too.
If you send me a file with all the new features I can also implement/update it.
Keep up the good work :)
Your work is so amazing I want to french kiss you.
I've used your stuff for a BattleTech RPG campaign for a few months now, and love the work you have done! If we could get windows added back, that would be awesome. The idea of toggleable building height is a great idea, too. Thank you so much for your work, it is all just incredible!
This thing is amazing, thank you!
Amazing! Ground plane and separate texture export would be amazing!
I feel like the houses are a bit too tall, so whenever I explore, I feel like I'm roaming 4-5 storey houses packed in a small space. Other than that, I love it
Научите, как импортировать? Я не понимаю как запустить 3D генератор и тем более , как импортировать туда свою карту.
Расскажите в чем проблема. Это приложение (City Viewer) у вас вообще работает? Модель города крутится или там просто пустой темный прямоугольник?
Is it possible to add gables to a city imported from MFCG? I'm having trouble with this file... https://drive.google.com/open?id=1mGmdUilOODNJA6X86qWowZQip9Te33hH
It appears to be working now. The only thing I did differently is to have gables enabled before copying the file from MFCG into City Viewer. Thanks!
I don't understand how to toggle auto rotation thank you for your help
just press the tilde key (`).
Thank you for adding gabled roofs!
Dropping a JSON file on to the viewer does not seem to work.

Send me your email address and I will. Also, I dont think its a file issue at all. I believe that it is a browser permissions issue. Look at the response I posted on the dev page.
I missed that message of yours. "The devicemotion events are blocked..." shouldn't be a problem, it's just a warning and it doesn't prevent the rest of the code from working.
I've uploaded a small update, which at least helps with Tazshelby2016's file. In that case it was invalid geometry in JSON.
So it still doesn't work for you? I'm out of ideas, your file is loaded normally for me. Maybe you should try another browser, maybe something is wrong with your browser's settings/permissions (as you said). But in this case there should be messages in the console, not just that "devicemotion" one.
Really good addition to MFCG which I'm a fan of. If you're still working on this it might be fun to have an option for building height
OMG! This is amazing!
This is amazing wow!
This is so cool. So many things you can do with it!
