Whilst that will prevent brown boxes, it also removes necessary light props, meaning RHW C networks and the DDRHW-4 lights won't work as intended.

Thankfully the bulk of the mod just re-uses the Maxis files, which LRM overrides, in other words it'll dynamically show matching lights to whatever LRM setup is in use, provided those are using the Maxis IDs. In this sense it would appear the bulk of the mod will work with older LRM versions.

However, specifically for the RHW-C networks, I needed an offset prop, which requires using a specific ID for the Lightpole Prop. These do not match with the IDs of LRM 4 so far as I can tell, but it would only take a quick edit to fix that.

All you have to do is find the particular light you want to use (ideally it would match the RHW Median Light in use). If you open the file LRMv4Props.dat in Reader, you can find the corresponding values from any of the Props is use, it's the 8th Rep under Resource Key Type 4 and should be easy enough to find, since it should always be DD##0000, only the ## differ for each particular light pole.

Now, Open the attached file and look at the first item (Exemplar), edit the 8th and 24th Reps (Red), changing FF to the value from LRMv4Props.dat. So for example, if I choose the LRM - NFSU Freeway Light - Generic - Orth to use (shown in image), I would change the Resource Key Type 4 entry as follows:

0x00000001,0x00000000,0x00000000,0xFFFBF0E0,0x27812821,0x5AD0E817,0xBADB57F1,0xDDFF0000,
0x00000001,0x00000000,0x00000000,0x00030000,0x27812820,0x5AD0E817,0xBADB57F1,0x5DFF77B1,
0x00000000,0x00000000,0x00000000,0xFFFBF0E0,0x27812821,0x5AD0E817,0xBADB57F1,0xDDFF0000

to

0x00000001,0x00000000,0x00000000,0xFFFBF0E0,0x27812821,0x5AD0E817,0xBADB57F1,0xDD000000,
0x00000001,0x00000000,0x00000000,0x00030000,0x27812820,0x5AD0E817,0xBADB57F1,0x5DFF77B1,
0x00000000,0x00000000,0x00000000,0xFFFBF0E0,0x27812821,0x5AD0E817,0xBADB57F1,0xDD000000

Once you've changed the Resource Key Type 4 entry, do the same for the Resource Key Type 4 XM property. Save the file and now it will work correctly with any light pole you can find.

Seems that this is not really as simple as I thought, but this could be worth trying.  

[rsc204 21,863]

Yeah, it's all to do with what's missing, if a Prop Exemplar (or other type) exists that links to a model that is not present in Plugins, you get a brown box. However, if the Prop Exemplar is also missing, then you simply get an invisible model without the Brown Box.

You only need to do this if you want to make use of the RHW-C networks and are not using LRM 5.

If you get really stuck, just tell me which of the props, (all are featured in the PDF manual), you want to be used for the C networks and I would happily take care of it. But I don't intend to go through and add every option, there are too many really.

Thanks, I really appreciate it! I'll play around with this   

[junspud 1,068]

In the off-chance it helps anyone else out I believe I spoke too soon, the prop was actually '9f9bbc47' (and its diagonal counterpart) listed as 'modified copy of 0x69ad0000' included in NAM as opposed to the 69ad prop itself, which I found out is in fact included in LRM4 and 5 and wasn't the source of the problem. I may be mistaken but after looking into the replacement set dat files the 9f9bbc47 prop doesn't seem to be covered by LRM4/5 at this time, at least in some of the option packages.

 

I don 't think I've seen it crop up again since overriding this one.

Found it by chance while scrolling through some of the families in PIMX with the LRM4 package installed and made sure all three ST dats were present.

[rivit 3,402]

Doesnt surprise me actually. Its quite a while since LRM 4 or 5 or any other light mod, and the network T21s for all the new networks haven't all been checked to make sure they actually get (correctly) overridden by LRM. Also new content isn't being produced by reusing the old IDs and items that originate in SC4 - often new exemplars appear when backward dependency to things in SC4 is the preferred way.

Its a pity, because it makes old mods break down whereas if they continued the original linkages they would just keep working. Not only that why have 4 versions of the same original SC4 prop.

hello, is this plugin still active? Has anyone had problems with the parks menu? this plugin it hits me and the game breaks and forces me to close windows

[rivit 3,402]

hello aom1550 - we will need a bit more info than you've given to be able to help - this mod does nothing to menus, just changes the look of street lights.

As a first step back to sanity, I suggest to remove the LRM mod - then see if you're back to what you expected to happen. If thats all oK then carefully try to put it back and record under what circumstances it goes pear shaped - if at all.

Do you mean while scrolling through the parks menu eventually the game freezes?

If you're using the Maxis LightCones file, I had this problem also and found out it's a known bug. A fix was posted earlier in the thread.. I can't find it though at the moment, I believe the original was corrupted and then reuploaded by rsc204. I'll attach it here as I can't locate the original post at the moment.

LRMv4_Models_LightCones_MaxisNite.zip

The dat file replaces the original 'LRMv4_Models_LightCones_MaxisNite.dat' file in the 'LRMv4 Models & Props' folder.

I think some other modified version were also uploaded previously in the thread and would also fix the crashing.

Also it was mentioned one of the Imaginian lights has an unsupported character in one of the exemplars which causes crashing, if that's the problem it's an easy fix but I think the original uploaded file became corrupted.

Along with the mandatory patch for the MaxisNite lightcones, the IM Brinasken lights fix was previously uploaded in this thread. However, since both have become corrupted, the original files are no longer useful, here are working versions of both fixes. The first is needed for all LRM 4 users who want to have MaxisNite lightcones, the latter only if you use the IM set of Ploppable Lights.

LRMv4_Models_LightCones_MaxisNite.zip

LRM RHW Median Lights - Set 09 - IM Brinasken.zip

2 of 3  and only 2.5 years later, honestly I don't know what was changed in the third file and have no desire to dig into it blindly.

In addition to the MaxisNite light cones posted by @rsc204, I have created another patch for LRMv4.0 to decrease the oversaturation of the MaxisNite light cones. It's uploaded here: LRMv4_Models_LightCones_MaxisNite_dim-patch-v2.zip and needs to load after the light cones file.

With my patch, the light intensity approximately follows an inverse square law. Before and After shots are attached below.

Hello, I have exactly the same problem: it freezes whenever I reach the light poles in the park menu.
Alas, the fix you attached didn't work. At least for me.

 

I guess I'll have to remove this mod until it is somehow fixed...

I believe when I did that, I missed a few. unfortunately I discovered later. I forgot about this, but I remember I fixed it further for my own personal use and it no longer crashes for me. I'll try and figure out how I did that again as it was a while ago, I believe I have the files with all of the instances removed/fixed.

 

Are you using the ploppable Imaginian lights set of lots? I think that's what was crashing mine while scrolling through the parks menu, I remember I went through the dat and removed the unsupported characters and it fixed it for me. Apologies if this is something unrelated... I think I still have it somewhere.

If you remove just the dat file for the Imaginian set of ploppable lots from the folder it might stop crashing. The exemplars have an unsupported character included and it causes the game to crash when you reach those lots in the menu.

I know I eliminated all of my crashing problems somehow at some point, apologies if I'm not remembering correctly.

Where can I find the ploppable lights?

I've reinstalled it twice in my plugins folder (through steam and documents) and I can't find anything related to the lights

[rsc204 21,863]

If you installed them, they should be selectable from the lower end of the parks menu.

Hello friends. I’ve been reading a lot this thread but couldn’t find if it is possible to change the light color to white for every road type, as currently if install the USA set for LRMV5 it gives me orange on commercial and some Bridges and white in LDresidential, which makes my nights a messy color soup. 
 

also, I’m curious of which file to install of the ones posted in this thread to have dimmed lights on LOTS, as every file attached to this post contains “LRMV4” or “MaxisNite” and I’m using lrmv5 and darknite.

 

thanks and sorry in advance for reviving post

Hello everyone! I hope I can get some support, because I don't know what else to do. So, before installing this Airport Mod my LRM was working flawlessly. Now, after installing that mod, or some (or more) of its dependencies (I suspect this), my LRM is completely broken. I'm attaching some screenshots of what's going on:

I'm using Project Symphony and this mod as well. Funny thing is, even removing the two mods didn't solve the problem, because when I tried that I had rainbow squares instead of the orange shade.

This mod included originally an overhaul of the LRM, not sure but the same would be true if you installed it as a dependency. It shouldn't actually be necessary either, because the original LRM uses the same IDs.

Long and short, removing what was added should revert to your previous setup.

Rainbow squares (test pattern), indicates an S3D model where the linked textures are not installed. The default LRM files included these textures, so not sure how they could not be present. I suspect some part of the conflicting override is still present or you've accidentally removed some LRM files.

Thanks for the reply! I had completely forgotten I wrote this, but anyway I solved the issue time ago (although I can't remember how, probably deleted the right file...). But still, thanks for the help^^

Can a version of this mod be made to remove all the streetlights? Or is that too big an ask?

Yes, it would require to modify all the exemplars for lampposts and light cones to point to a blank model. It's tedious but very easy.
