Sorry guys, too fast. Texture issues came from GrassNAM Mod Berner Oberland. After deleting the folder, textures went back to normal. 

Do you mean TGN? Honestly I don’t know if other mods with these textures. The change in NAM occurred after the last update and it will be corrected eventually. Rather than delete the entire TGN mod, I can give you some patches in the meantime if you prefer.

Yes, I meant TGN.

Funny enough I started playing SC4 two weeks ago after 15 years of absence  So I rated NAM higher than TGN, therefor I deleted TGN completely.

I don't want to take your time, still taking more time on STEX than actual playtime in SC4 because I need to gather a whole new Plugin folder. I just wanted to try TGN out, nothing essential for me (yet), I think I can wait for an update (if there will be one in the future). But thank you very much for the offer

How can I make an intersection or interchange between a diagonal RHW4 and a diagonal AVE4?  Any help would be greatly appreciated. And are there any pics or videos of this?  

[Tarkus 6,932]

If you're talking about an intersection, where the two are meeting directly, at-grade, you can simply just drag the two together to form the intersection, just as you would with, say, an Avenue and a One-Way Road.  Note that only 4-way "+"-intersections are possible. T-intersection functionality does not exist at present (regardless which network ends at the other).

For a grade-separated interchange with ramps and the like . . . there are no elevated diagonal ramp interfaces for the RHW presently, so it's easiest if the Avenue is elevated and the RHW is at ground.  I technically have an RHW-6S here, so I could have the dedicated exit/entrance lanes with the Type E1 ramps, but the same premise applies.  There are diagonal height transitions for both the MIS ramps and the Avenue Viaducts, which you can use to connect the two.  Took me a little trial and error (the top part of the interchange is bothering me a bit), but this should give you some idea of what's possible at present.

Also note all ploppable items here are FLEX pieces--no old-school puzzle pieces involved.

Thank you @Tarkus. The diagonal ramped intersection is exactly what I'm needing to build. This information and the picture are perfect. Thanks again! And @CorinaMarie too.

Just found the code that seems to be causing that.  It's probably actually been like that for years, and no one's caught it until now.

Thanks @Tarkus and here another BUGGY was found!

I hope will fix on future version!

Aside from the OWR-3 breakage, most of those situations are not bugs, as those intersections aren't and won't be supported due to lane math.  RD-6, for instance, has 3 lanes in each direction, whereas the default Road network has 2 total lanes.  If you were to end a RD-6 at a T-intersection with a Road, on the 3-lane half of the RD-6 that's approaching the intersection inbound, one lane could turn left, one lane could turn right . . . but there's nowhere for that third lane to go, except to cause a nasty accident from making a nonsensical turn.  There's one too many lanes on the RD-6 (or one too few on the Road) for that intersection to work.

The NWM Technical Data section on the online NAM Documentation site goes into which situations are and are not supported, on the table here.  "T-End Min" shows the minimum number of lanes that must be on the thru-network in order for that network to be able to end at it, while "T-In Max" looks at the thru-network, and shows the maximum number of approach lanes that can end at a T-intersection with that particular network.  RD-6's "T-End Min" is 3.  The Road network and OWR network only have 2 total lanes, so they fail to meet "T-End Min" for RD-6.

Those Avenue situations you've shown are the "Short-Ts" rather than the "Long-Ts" (where the network fully accesses both halves of the Avenue), so the access is only to 2 lanes, not all 4.  The only multi-tile NWM networks that have a "T-End Min" of 2 are the TLA-5 (the center turn lane's functionality is optional) and the RD-4.

As there are Road-based NWM networks that do have enough lanes for RD-6 to end at them (i.e., ARD-3 and NRD-4), and those require a base Road intersection to override, the intersection does have to exist in some form in order for that to happen, but those situations are intentionally designed to be non-functional dummy intersections, so no one can build something that doesn't add up in terms of lane math.

Am I going to royally break anything if I insist to use TSCT with current NAM editions? Or if I iLive-mod the values it included?

If you use TSCT it means breaking the traffic simulation.

The only solution is to manually edit the traffic simulator file.

However what kind of modifications do you need to make?

To be fair, I always change only the mass transit usage ratio (MT, car, fastest). Seldom, monthly fares / sim / tile too.

Using iLives Reader, you need to modify these three elements on the Traffic Simulator DAT file included in your NAM installation:

(In case the image doesn't load, they are called Travel strategy percent Wealth, with different amounts of money signs depending on the wealth level, and have the hex IDs 0x4953E8A4 to 0x4953E8A6).

Those values are an array of three integer numbers in hexadecimal, going from 0x00 (0 in decimal) to 0x64 (100 in decimal). You can adjust the values however you like, provided that they add up to 0x64 in hexadecimal. If you're using iLives Reader 1.5.4, you can simply switch from hexadecimal to decimal to save you the hassle, but you cannot on version 0.9.3. The values, in order, correspond to the preference for Mass Transit, Driving, and whatever is Fastest. Keep in mind, as well, that the last option is more computationally heavy than the others, so you might experience some extra lagging if you raise that one very much.

Hi everyone this is my first time here and making an account. I remember I installed NAM a long time ago but don't have it anymore, I recently decided to look into it again for fun.
I saw that NAM 48 had a virus or something on moddb in these forums and got anxious about downloading even from here. My question is... is it safe to download NAM lite
from here? I know that it was the full version that had the virus/malware but I want to know for sure. 

Thank you in advance everyone.

NAM is no longer distributed on moddb. So the later version (NAM 49 rev1 & NAM Lite 4) are distributed on Simtropolis,SC4Evermore and Githhub which are the official distribution channels

Hello, why do the NWM starter-pieces have farmland textures when you build around them?

I've tried digging through the files, but I can't find anything to change this.

Spoiler

Thanks in advance.

For technical reasons, the starters are internally implemented as intersections between two networks. The OWR-1 starter is based on an intersection between OWR and Rail, which causes this problem, as Rail prefers dirt over sidewalks. It's a long-standing issue that's never been addressed. You can't do anything about it really, without re-implementing the starter itself using different networks.

[Lucario Boricua 7,028]

@Aka

If your OWR-1 network area is sufficiently large, you can remove the starter, the override can maintain itself in such situation. A lot harder to do if the OWR-1 segment you're using is for a really short segment (typically 6 cells or less in length).

Hi Friends,

I'm new to Simtropolis - I hope this message is in the right place!

I'm having trouble downloading NAM49, and I'm hoping someone might be able to help. Many thanks to all involved in the NAM project - it greatly improves the base game!

- My system: Windows 10, 8GB RAM, 600+ GB free; SimCity 4 Deluxe (from Steam, Ver 1.1.641.0)

- Previously used NAM (NAM36) without issue; installation was a snap

What I've done so far:

- Deleted NAM36

- Clicked NAM49 download on Simtropolis - re-directs to SC4 Evermore; clicked download button on SC4 Evermore

- 'Opened' .zip file (takes a while)

- Used 'Extract All' and saved files to 'Documents' - screenshot of files:

- Installed AdoptOpen JDK JRE

- Double clicked NetworkAddonMod_Setup - nothing happened

- Right-clicked NetworkAddonMod_Setup and selected 'Open With' Open JDK - nothing happened

This is where I'm stuck. Any help will be very much appreciated! I've tried uninstalling and re-installing SC4 from Steam, and installing Java from Oracle, but neither action seems to make a difference.

Many, many thanks,

Dee

[Tarkus 6,932]

If you have Java installed and the .jar extension is associated with it (which, judging by the icon on the file in your screenshot, it is), it should be possible to just run the .jar by double-clicking it. 

There were some recent revisions to the NAM's installer (which was originally back in 2009 built an ancient version of Java), and while I don't know that they necessarily impacted compatibility with the different versions of Java, it's possible the Java 11 copy that's bundled with the NAM won't work anymore.  I've actually had that issue with an older Java application of my own, of roughly mid-2010s vintage, which won't run with the Java 21 distro I'm currently running from Adoptium (but the NAM installer runs just fine with it).  I'd give that a try.  Having multiple Java installations could have an impact, too.

Reinstalling the game won't help, as the issue isn't with SC4 itself--rather, it's something to do with your Java installation and with the NAM installer.

I will note that we are looking to go back to using an NSIS-based .exe-based installer for NAM 50, as the upcoming changes to the mod's architecture (including the inclusion of DLL-based functionality) are better served that way.

Hi Tarkus,

Thanks so much for your message.

I tried Java from Adoptium, including with a fresh download/unzip - alas, no success. This one has got me beat.

But that's ok - I'll keep my eyes peeled for NAM50! Thanks again for all the work you do.

Dee

Edit: I should add that I'm no computer super-user, but I'm 99% sure I don't have multiple Java installations. Thanks again.

This is not really a solution, but maybe you can try confirming if the newer Java is installed properly.
Open your Command Prompt (cmd), type in this line, and then press Enter.

java -version

It'll show the version of Java that's being used on your computer.
If you installed the one from the link shared by Tarkus, it should show you the version is "21.0.7".
But if you got a lower one, close the cmd, try reinstalling java, and check the version again.

[Dee 1 0]

Thanks, bhmantan.

I can confirm it was Ver 21.0.7 that I used (I tried again today). The best result I get when attempting to run the .jar file is a window that pops open for a split second then immediately closes (I believe it's Java attempting to run).

Perhaps there's a conflict with Windows Defender or some other program on my system.

In any case, I'm due to update my machine soon (with Windows 10 reaching end-of-life), so I'll try again then or hold out for NAM50.

Thanks again.

Hi! Ive recently came back to playing SimCity 4 after about 600 hours gameplay and 6 years since I last booted it up (and a new PC so none of my old cities are available).

I have installed the latest NAM but I cannot seem to get the new transport map in the world view. It is still showing the OG Maxis one.

Have I missed something?

Thanks in advance!

If I'm understanding correctly, you'll need to enter and save each city if you want the color patterns of pre-existing networks in those cities to match the new NAM colors on the map legend.

[Lucario Boricua 7,028]

Each city's regional map views (satellite and transportation) is a PNG image that gets updated every time the city goes through a full save. If you change terrain mods or the transportation map legend, you gotta save and exit to region to get the desired changes.

Dee,

My system is similar to yours: Windows 10, 16 GB RAM, SimCity 4 Deluxe (from Steam, Ver 1.1.641.0)

Screen shot for my installation:

For starters, I download new versions of NAM to my Downloads folder in Windows Explorer. Since NAM 47, I right-click on the NAM download and select “open with” to use Windows Explorer to open the download, not 7-zip which I usually use to extract files. I then double-click on the NAM-Setup .jar file to run the installer. These steps are what work for me.

Hi, I need some help! Everything is going smoothly, I have an avenue running under my rail etc, but I can't find an Avenue underpass piece that goes under the elevated High-Speed Rail. Does one exist? If not, how can I connect my avenues?

Thank you!

 

 

[rsc204 21,808]

If it does, it'll be found under the HSR menu and not with the other FLUPs.
