#sims 2: tutorial

[jodeliejodelie]

It's finally here, my tutorial for adding new terrain types to The Sims 2!

This was tricky to write so I hope I documented everything correctly!

You can also get the guide as a PDF (including tutorial files) at SFS.

Tutorial: Adding a custom terrain and road in The Sims 2

By JodelieJodelie

Version 1.0

13-10-2025

This is a tutorial for adding new custom terrains with roads to the four existing terrains (temperate, desert, concrete, dirt) in The Sims 2.

This tutorial requires knowledge of SimPE and editing files.

Required software

The Sims 2

SimPE

A text editor such as Notepad

A hex editor such as https://hexed.it/

Files that will be edited

The files you will edit should be in the folder of your latest EP/SP. Since I have the Ultimate Collection (UC) I will refer to the Mansions & Gardens subfolder (SP9) in Fun with Pets folder.

In my case, my install folder looks like: C:\Program Files (x86)\EA Games\The Sims 2 Ultimate Collection. I’ll refer to the installation path as ~.

~\Fun with Pets\SP9\TSData\Sys\NeighborhoodTerrain.ini

~\Fun with Pets\SP9\TSData\Res\Catalog\Scripts\terrainPaints.txt

~\Fun with Pets\SP9\TSData\Res\Materials\Materials.package

OR if you have shaders installed such as LazyDuchess’ Lot Lighting Fixes or the Multi Road Mod (1, 2) you’ll need to edit those instead.

The particular shaders we’ll be editing are:

Instance 0xFF6BE964: Predefined neighborhood materials

Instance 0xFF439C10: Shaders for lot skirt

Optional: Instance 0xFF1AFA1C: Shaders for terrain tiles

Tutorial files

I have uploaded a package with texture files for a snow terrain based on this dirt default by Freezer Bunny (uploaded by Shastakiss). The road texture is based on the Rural Charm road by Criquette.

Download at SFS.

The terrain file contains the following textures:

lottexture-canvas-snow_detail_txtr

lottexture-canvas-snow_txtr

snow-rough_txtr

snow-rough-hsnow_txtr

snow-rough-lsnow_txtr

snow-rough-light_txtr

snow-rough-light-hsnow_txtr

snow-rough-light-lsnow_txtr

snow-smooth_txtr

snow-smooth-hsnow_txtr

snow-smooth-lsnow_txtr

snow-smooth-rougher_txtr

snow-smooth-rougher-hsnow_txtr

snow-smooth-rougher-lsnow_txtr

The road file contains the following textures:

lotskirtroad_snow_00000304_txtr

lotskirtroad_snow_00000304_hsnow_txtr

lotskirtroad_snow_00000304_lsnow_txtr

lotskirtroad_snow_00000f04_txtr

lotskirtroad_snow_00000f04_hsnow_txtr

lotskirtroad_snow_00000f04_lsnow_txtr

lotskirtroad_snow_00004b04_txtr

lotskirtroad_snow_00004b04_hsnow_txtr

lotskirtroad_snow_00004b04_lsnow_txtr

lotskirtroad_snow_00005704_txtr

lotskirtroad_snow_00005704_hsnow_txtr

lotskirtroad_snow_00005704_lsnow_txtr

lotskirtroad_snow_00020704_txtr

lotskirtroad_snow_00020704_hsnow_txtr

lotskirtroad_snow_00020704_lsnow_txtr

snow_roads_00000304_txtr

snow_roads_00000304_hsnow_txtr

snow_roads_00000f04_txtr

snow_roads_00000f04_hsnow_txtr

snow_roads_00004b04_txtr

snow_roads_00004b04_hsnow_txtr

snow_roads_00005704_txtr

snow_roads_00005704_hsnow_txtr

snow_roads_00020704_txtr

snow_roads_00020704_hsnow_txtr

Notice how all the textures have the word “snow” in them. If you want to create your own terrain, you can replace these with a word of your choosing (but don’t replace hsnow and lsnow, these are needed when it’s snowing in the game). Don’t forget to click “fix TGI” and “Commit” in SimPE if you do.

Step 1. Editing NeighborhoodTerrain.ini

Make a back-up of your NeighborhoodTerrain.ini file.

Open the file in a text editor.

You will need to add new text in three places.

First edit: PaintInfos

Under [PaintInfos] you will find all the terrains in your game. The last one will be the concrete terrain.

; for concrete terrain 0x13=0.9,concrete-smooth,1, lottexture-concrete-01, 0,1, 26,0 0x14=0.9,dirt-grey,1, lottexture-concrete-01, 0,1, 26,0

You will need to add your own terrain under this one. You can use one of the other ones as inspiration. I followed the dirt formatting.

Very importantly:

You must increase the numbers at the beginning of the lines

You must write down the right texture names

So that means for our tutorial terrain it will look like this:

; for snow terrain 0x15=0.9,snow-smooth,1, lottexture-canvas-snow, 0,1, 48.0,0 0x16=0.9,snow-smooth-rougher,1, lottexture-canvas-snow, 0,1, 32.0,0 0x17=0.9,snow-rough-light,1, lottexture-canvas-snow, 0,1, 32.0,0 0x18=0.9,snow-rough,1, lottexture-canvas-snow, 0,1, 48.0,0

Add it after the concrete terrain.

Second edit: TerrainTypeInfos

Under [TerrainTypeInfos] you will need to add your terrain with 0x10 and 0x11. These are the cliff and beach paints. Technically this means you could have different cliff and beach paints per terrain. But that’s for another time.

So the format is Name=Cliff_Paint_ID,Beach_Paint_ID.

In our case this means you will add the following line under the concrete one:

Snow=0x10,0x11

Third edit: PaintMapTable

In this last edit you will need to add a paintmaptable of your new terrain. This map will determine at what height which texture will get applied.

Copy a map of a terrain. I used the dirt one as my inspiration.

[PaintMapTable_Dirt] 00=0x12,0x12,0x07,0x09,0x09,0x09,0x08,0x09,0x09,0x08,0x09,0x09,0x08,0x08,0x09,0x09, 01=0x12,0x12,0x07,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08, 02=0x12,0x12,0x07,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09, 03=0x12,0x12,0x07,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08, 04=0x12,0x12,0x07,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09, 05=0x12,0x12,0x07,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08, 06=0x12,0x12,0x07,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09, 07=0x12,0x12,0x07,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08, 08=0x12,0x12,0x07,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09, 09=0x12,0x12,0x07,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08, 10=0x12,0x12,0x07,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09, 11=0x12,0x12,0x07,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09, 12=0x12,0x12,0x12,0x12,0x12,0x12,0x12,0x12,0x07,0x07,0x07,0x09,0x09,0x08,0x08,0x09, 13=0x12,0x12,0x12,0x12,0x12,0x12,0x12,0x12,0x07,0x07,0x07,0x08,0x08,0x09,0x09,0x09, 14=0x12,0x12,0x12,0x12,0x12,0x12,0x07,0x12,0x07,0x07,0x07,0x08,0x09,0x09,0x09,0x09, 15=0x12,0x12,0x12,0x12,0x12,0x07,0x07,0x07,0x07,0x07,0x07,0x08,0x09,0x09,0x09,0x09, 16=0x12,0x12,0x12,0x12,0x12,0x07,0x07,0x07,0x07,0x07,0x07,0x08,0x09,0x09,0x09,0x09, 17=0x12,0x12,0x12,0x12,0x12,0x07,0x07,0x07,0x08,0x08,0x08,0x09,0x09,0x09,0x09,0x09, 18=0x12,0x12,0x12,0x12,0x12,0x07,0x08,0x08,0x08,0x08,0x09,0x09,0x09,0x09,0x09,0x09, 19=0x12,0x12,0x12,0x12,0x12,0x07,0x08,0x08,0x08,0x08,0x08,0x09,0x09,0x09,0x09,0x09, 20=0x12,0x12,0x12,0x07,0x12,0x07,0x08,0x08,0x08,0x08,0x09,0x09,0x09,0x09,0x09,0x09, 21=0x12,0x12,0x07,0x07,0x08,0x08,0x08,0x08,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09, 22=0x12,0x12,0x07,0x07,0x08,0x08,0x08,0x08,0x08,0x09,0x09,0x09,0x09,0x09,0x09,0x09, 23=0x12,0x12,0x07,0x07,0x08,0x08,0x08,0x08,0x08,0x09,0x09,0x09,0x09,0x09,0x09,0x08, 24=0x12,0x12,0x12,0x07,0x08,0x08,0x08,0x09,0x09,0x09,0x08,0x09,0x09,0x09,0x09,0x09, 25=0x12,0x12,0x12,0x07,0x08,0x08,0x08,0x09,0x09,0x09,0x09,0x08,0x08,0x09,0x09,0x09, 26=0x12,0x12,0x12,0x12,0x08,0x08,0x08,0x08,0x09,0x09,0x09,0x09,0x09,0x09,0x09,0x09, 27=0x12,0x12,0x12,0x12,0x08,0x08,0x09,0x09,0x09,0x09,0x09,0x08,0x09,0x08,0x09,0x09, 28=0x12,0x12,0x12,0x12,0x08,0x12,0x08,0x12,0x08,0x12,0x08,0x08,0x08,0x08,0x08,0x09, 29=0x12,0x12,0x12,0x12,0x07,0x07,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x08,0x09,0x08, 30=0x12,0x12,0x12,0x12,0x07,0x07,0x07,0x07,0x07,0x07,0x07,0x07,0x07,0x07,0x08,0x09, 31=0x12,0x12,0x12,0x12,0x07,0x07,0x07,0x07,0x07,0x07,0x07,0x07,0x07,0x08,0x07,0x08,

There are two things you will need to change.

First the name: [PaintMapTable_Snow]

Second, you will need to change all the numbers after the x=. These reference the numbers we used in the first edit in the PaintInfos.

; for snow terrain 0x15=0.9,snow-smooth,1, lottexture-canvas-snow, 0,1, 48.0,0 0x16=0.9,snow-smooth-rougher,1, lottexture-canvas-snow, 0,1, 32.0,0 0x17=0.9,snow-rough-light,1, lottexture-canvas-snow, 0,1, 32.0,0 0x18=0.9,snow-rough,1, lottexture-canvas-snow, 0,1, 48.0,0

So that means:

0x07 will be replaced by 0x15

0x08 will be replaced by 0x16

0x09 will be replaced by 0x17

0x12 will be replaced by 0x18

I suggest copying the PaintMapTable to another Notepad and replace them with Replace All (Ctrl H).

The result:

[PaintMapTable_Snow] 00=0x18,0x18,0x15,0x17,0x17,0x17,0x16,0x17,0x17,0x16,0x17,0x17,0x16,0x16,0x17,0x17, 01=0x18,0x18,0x15,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16, 02=0x18,0x18,0x15,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17, 03=0x18,0x18,0x15,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16, 04=0x18,0x18,0x15,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17, 05=0x18,0x18,0x15,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16, 06=0x18,0x18,0x15,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17, 07=0x18,0x18,0x15,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16, 08=0x18,0x18,0x15,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17, 09=0x18,0x18,0x15,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16, 10=0x18,0x18,0x15,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17, 11=0x18,0x18,0x15,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17, 12=0x18,0x18,0x18,0x18,0x18,0x18,0x18,0x18,0x15,0x15,0x15,0x17,0x17,0x16,0x16,0x17, 13=0x18,0x18,0x18,0x18,0x18,0x18,0x18,0x18,0x15,0x15,0x15,0x16,0x16,0x17,0x17,0x17, 14=0x18,0x18,0x18,0x18,0x18,0x18,0x15,0x18,0x15,0x15,0x15,0x16,0x17,0x17,0x17,0x17, 15=0x18,0x18,0x18,0x18,0x18,0x15,0x15,0x15,0x15,0x15,0x15,0x16,0x17,0x17,0x17,0x17, 16=0x18,0x18,0x18,0x18,0x18,0x15,0x15,0x15,0x15,0x15,0x15,0x16,0x17,0x17,0x17,0x17, 17=0x18,0x18,0x18,0x18,0x18,0x15,0x15,0x15,0x16,0x16,0x16,0x17,0x17,0x17,0x17,0x17, 18=0x18,0x18,0x18,0x18,0x18,0x15,0x16,0x16,0x16,0x16,0x17,0x17,0x17,0x17,0x17,0x17, 19=0x18,0x18,0x18,0x18,0x18,0x15,0x16,0x16,0x16,0x16,0x16,0x17,0x17,0x17,0x17,0x17, 20=0x18,0x18,0x18,0x15,0x18,0x15,0x16,0x16,0x16,0x16,0x17,0x17,0x17,0x17,0x17,0x17, 21=0x18,0x18,0x15,0x15,0x16,0x16,0x16,0x16,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17, 22=0x18,0x18,0x15,0x15,0x16,0x16,0x16,0x16,0x16,0x17,0x17,0x17,0x17,0x17,0x17,0x17, 23=0x18,0x18,0x15,0x15,0x16,0x16,0x16,0x16,0x16,0x17,0x17,0x17,0x17,0x17,0x17,0x16, 24=0x18,0x18,0x18,0x15,0x16,0x16,0x16,0x17,0x17,0x17,0x16,0x17,0x17,0x17,0x17,0x17, 25=0x18,0x18,0x18,0x15,0x16,0x16,0x16,0x17,0x17,0x17,0x17,0x16,0x16,0x17,0x17,0x17, 26=0x18,0x18,0x18,0x18,0x16,0x16,0x16,0x16,0x17,0x17,0x17,0x17,0x17,0x17,0x17,0x17, 27=0x18,0x18,0x18,0x18,0x16,0x16,0x17,0x17,0x17,0x17,0x17,0x16,0x17,0x16,0x17,0x17, 28=0x18,0x18,0x18,0x18,0x16,0x18,0x16,0x18,0x16,0x18,0x16,0x16,0x16,0x16,0x16,0x17, 29=0x18,0x18,0x18,0x18,0x15,0x15,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x16,0x17,0x16, 30=0x18,0x18,0x18,0x18,0x15,0x15,0x15,0x15,0x15,0x15,0x15,0x15,0x15,0x15,0x16,0x17, 31=0x18,0x18,0x18,0x18,0x15,0x15,0x15,0x15,0x15,0x15,0x15,0x15,0x15,0x16,0x15,0x16,

Add this map after the concrete one.

And that’s the last edit of the NeighborhoodTerrain.ini. Don’t forget to save your file!

Step 2. Editing terrainPaints.txt

Make a back-up of your terrainPaints.txt file.

Open the file in a text editor.

You will need to add new text in one place.

Scroll down, you will see the following texts:

terrainPaint "lottexture-concrete-01" brushWidth 3 notInCatalog terrainTypeSoundSuffix "grass" terrainPaint "lottexture-canvas-dirt" brushWidth 3 notInCatalog terrainTypeSoundSuffix "grass"

Add your own terrain after these.

terrainPaint "lottexture-canvas-snow" brushWidth 3 notInCatalog terrainTypeSoundSuffix "grass"

Note, I don’t know what other terrainTypeSoundSuffix types exist.

Save the file.

Step 3. Editing shaders

This step depends whether you use shader mods or not. If you don’t, you will need to edit ~\Fun with Pets\SP9\TSData\Res\Materials\Materials.package. Otherwise, you will need to edit your mods.

Regardless, make back-ups.

Predefined neighborhood materials

Open the Materials.package or your mod.package in SimPE.

Look for instance 0xFF6BE964.

Scroll down and add the following to the other NHoodRoadMaterials.

#Snow create NHoodRoadMaterial(neighborhood-roads-Snow-00005700 snow_roads_00005704) create NHoodRoadMaterial(neighborhood-roads-Snow-00020700 snow_roads_00020704) create NHoodRoadMaterial(neighborhood-roads-Snow-00000f00 snow_roads_00000f04) create NHoodRoadMaterial(neighborhood-roads-Snow-00000300 snow_roads_00000304) create NHoodRoadMaterial(neighborhood-roads-Snow-00004b00 snow_roads_00004b04)

Click “Commit” and save your file.

Shaders for lot skirt

Open the Materials.package or your mod.package in SimPE.

Look for instance 0xFF439C10.

Scroll down and add the following to the other LotSkirtRoadMaterialInstances.

#Snow create LotSkirtRoadMaterialInstance(lotSkirtRoad_Snow_00005700 lotskirtroad_snow_00005704) create LotSkirtRoadMaterialInstance(lotSkirtRoad_Snow_00020700 lotskirtroad_snow_00020704) create LotSkirtRoadMaterialInstance(lotSkirtRoad_Snow_00000f00 lotskirtroad_snow_00000f04) create LotSkirtRoadMaterialInstance(lotSkirtRoad_Snow_00000300 lotskirtroad_snow_00000304) create LotSkirtRoadMaterialInstance(lotSkirtRoad_Snow_00004b00 lotskirtroad_snow_00004b04)

Click “Commit” and save your file.

Optional step

This step is not required to make your new terrain functional but will improve how it looks, especially if you have a texture with multiple colors or a grid.

The edit will need to be done in another shader, namely the Shaders for terrain tiles (instance 0xFF1AFA1C). Note: these values apply to all other terrains and terrain paints.

So again, open the Materials.package or your mod.package in SimPE.

Directly underneath terrainMatDiffCoef you will find the following.

# Specifies the number of tiles over which the paint & bump textures should be applied. setf  canvasDetailTextureScale            4 setf  canvasBaseTextureScale             20 setf  paintTextureScale                  20 setf  paintDetailTextureScale            4.0 setb  hasCutout false

These settings determine the size of both the terrain and terrain paints. For some mysterious reason, the developers put the values at 4. This means that the terrains will span 4x4 tiles. This means it will never line-up with the neighborhood terrain that is visible from the lot.

The default 4x4, this makes lining up textures difficult.

By editing it to 5x5, you can line up textures better.

As you can see, by increasing the texture by 5x5 it will be easier to make matching terrain defaults.

So change the values to the following.

# Specifies the number of tiles over which the paint & bump textures should be applied. setf  canvasDetailTextureScale            5 setf  canvasBaseTextureScale             20 setf  paintTextureScale                  20 setf  paintDetailTextureScale            5.0 setb  hasCutout false

Click “Commit” and save your file.

Step 4. Changing the terrain in your neighborhood

It’s time to start the game!

Either select an existing neighborhood or create a new one. If you want to apply it to an existing neighborhood I recommended creating a back-up.

When in the neighborhood, use CTRL + SHIFT + C to open the cheatconsole

Type “Terraintype Snow” and hit Enter.

The terrain will change, but will look a bit weird. That will fix itself when you either reload the neighborhood or restart the game.

But we’re not done yet, we need edit some values in SimPE.

Close the game if you haven’t already.

Step 5. Changing the road with SimPE

I learned about this from this thread on ModTheSims.

Open SimPE and use the Neighborhood Browser (via Tools) to open your neighborhood.

Extract the Neighborhood Memory (NGBH) and save it somewhere as SnowTutorial.simpe.

Open the .simpe file with a hex editor. I use an online version: https://hexed.it/.

Go to byte 14. This will have a number. This number corresponds with the number of letters in your terrain. In our case “snow” has 4 letters, so this value will need to be 4.

Starting at byte 18 you will find the letters of the terrain name. Depending on the length of the current terrain and the one you need, you might have to remove or add bytes. Replace the text with the name of your terrain and add/delete bytes if needed.

It will look like this in hexed.it:

Save the file and give it another name, such as SnowTutorialEDIT.simpe.

Return to SimPE and NGBH and replace (right click) the NGBH with the edited version. Click save.

Close SimPE and start the game again to check on your neighborhood.

If everything went alright you now have a snowy neighborhood terrain and matching road!

Note: any existing lots will need to be picked up and placed again. This will reset the terrain.

Result

I currently don’t have a lighting mod. Below you can see lot and neighborhood terrain comparisons per season. The difference is biggest for summer.

It’s not perfect, for instance snow during winter will do this to the terrain and neighborhood road from lot view. Maybe I’ll figure out how to fix this another time.

That was it!

Hey, sorry if I'm mistaken but your entry for room with a view looks like it's built on a lot foundation... if that's the case, could you share how you did it?

Hi anon! Yes it’s built on a minideck!

I got the idea from this tutorial by Shastakiss :)

Tutorial: Neighborhood Fog

Somebody asked me to make a tutorial about the fog object I made, so here it is! Sadly I don’t think this will be handy for other neighborhood decorations but you never know.

Step 1. Open SimPE.

Step 2. Open the Object Workshop.

Step 3. Click Start (Open is to recolor or clone custom content, Start is for Maxis objects). It will take a short while to load everything.

Step 4. Go to Other -> Neighborhood -> Effects -> Clouds.

Step 5. Click Next (with the blue arrows).

Step 6. You now have a window that allows you only to clone the object (neighborhood deco can’t be recolored, every recolor must be a new clone). Make sure you have selected the default settings and click Start.

Step 7. Now you can give the object a new name, but I think you need to change it somewhere else in SimPE to have the new name show up in the game. (I forgot to change the name of my fog object so I don’t really know). Click Finish.

Step 8. You get a pop-up screen where you can change some names, it’s not really necessary. I changed mine to “fog” anyway. Click Update to have the change take effect and click OK to continue.

Step 9. Now you get a window where you’re asked to save the file.

Step 10. Now you can change the file. If you look at some of the file names you will see the word “neighborhood boulder”. For some reason Maxis coded the effects neighborhood deco in such a way you can’t extract the effects themselves, but only the rock that they’re linked to. This is the reason why nobody has been able to make recolors of the neighborhood flowers and terrain patches for instance. You can extract the GMDC (geometric data container) all you want, but you will always end up with that rock. Also, the texture images will only show textures of the rock. I did replace the rock with a simple 2D sheet, which I extracted from Chemic’s “no rock effects”. This way I have no rock when placing the effect.

Maybe SimPE is to blame, but my money is on Maxis. It wouldn’t be the first time they would code something strange (if you want to change your terrain type in post neighborhood creation you have to dig around in the neighborhood memories for example).

Step 11. I’m not sure how GUIDs are distributed among neighborhood deco, but usually SimPE generates a GUID if I remember correctly. I actually gave my fog object a new GUID manually just to be sure, which I based on my GUID range determined by SimPE. The GUID for neighborhood deco is stored in the XNGB (see resource tree). Click on Plugin View on the bottom to actually see the resource and change the guid if you want or not.

Step 12. Now we’re at the part where I did the “important” work: flipping the clouds 180 degrees, so that instead of showing up in the air, they would show up on the land. This was basically a case of good luck, because I had no guarantee the clouds would be the right height.

I did this part in the Resource Node (CRES) page. In the Plugin View click on the drop down menu and select “0x4 cloud_slot etc.”.

You now have some XYZ coordinates stuff.

When I was making the object I basically messed around with a lot of these settings. I found out that you could use the Rotation to rotate the object around different axes.

This is how I learned I needed to flip the clouds on the X axis (I think the Y-axis might’ve done the trick as well). So next thing I did was change the Angle box to 180 and the X box to 1. (I also tried to mess around with the translation values but it didn’t change anything for me, but maybe I didn’t use the right values).

Click commit and save the file. Congratulations, you just made some fog!

Anyway, like I said, this tutorial is probably not very helpful with regard to other objects. But still, it’s pretty cool I figured out a way to do this.
