#ts3 default replacement tutorial

Search "food" on s3oc.

You will get results like this. Food that can be cloned are Hamburger, Hotdog, Fries (Seasons EP). I choose Hamburger because it's Base Game and it's resembling custom food we want to create.

"Clone or Fix..."> Don't tick Renumber > Start.

Save the package. Open the package on TSR Workshop.

Open TSR Workshop > Create New Project > New Import> Next > Browse EA Burger .package > Next > Next > OK.

You will get Burger mesh preview. Take a look at Mesh tab.

Then see the Group 0 and Group 1. Both have GeoStates.

What is Group 0? What is Group 1?

If you check the the burger's .s3asc exported from s3pe or .wso exported from TSRW

You will see Group 0 is the food mesh as main mesh and Group 1 is the plate.

Go back to TSR preview. You see there are 4 GeoStates under Mesh from Group 0 tab.

By default, the Burger meshes (Full, Half, Empty) are combined into one.

Click each GeoState, from top to bottom.

0x95A36FFE is Full state

0x8A6C4E39 is Half state

0x4DB2D3D2 is Empty State

0x35B26CCB is Full state

✳️ Step 5: Create your edited mesh

Import MODL file (with format .s3asc) of Egg Rolls you exported from s3pe from Step 2 into Milkshape 3D via Sims 3 Object Import by Wesley Howe. From Milkshape, export .obj file to your favourite 3D software to make .obj file as base mesh for your edited mesh.

Create 3 States: Full, Half, Empty.

Export uvmap to editing image software to create the texture.

After you are done and satisfied with your mesh, export your custom mesh only without plate, Full, Half, Empty states in .obj format. Hide EA plate and EA's base mesh before exporting.

✳️ Step 6: Create texture

Import uvmap from your 3D software. Create texture, save in .dds format with the same name as original name of .dds exported from s3pe.

✳️ Step 7: Bone Assignment, Make Group & Export to .wso

Open Milkshape 3D. Import .s3asc of original EA Egg Roll "foodEatEggRolls_filebase.s3asc" from Step 2. Click Joints Tab, tick box "Draw vertices with bone colors" to enable bone colours.

The food shows Purple colour, the plate shows Yellow colour.

*Note that this .s3asc was imported from year 2023, the original colours are like these. If in this recent year 2025 shows different colour such as the plate is Purple, please follow this example, assign the plate Yellow colour, because my method using this Yellow bone colour has been working successfully.

Then import .obj of your edited mesh from 3D software. Delete materials of custom mesh, select custom mesh, regroup, rename to group00.

Your main task is copy Bone Assignment from original EA mesh to your edited mesh.

Check the codes on Joints tab, there are 3. Click each code then click "Assign" to see what is the Bone colour to determine rig for functionality of the object in the game.

0xFEAE6981 --> Yellow 0xCD68F001 --> Purple 0xD0DECA8E --> Light Blue

We will assign the custom mesh with Purple colour, therefore, select the custom mesh, select 0xCD68F001, assign. The custom mesh colour will turn Purple.

After you are finished with the Bone Assignment (Main Mesh is purple, plate is yellow), make sure the groups are correct. Group 00 ---> main mesh. Group 01---> plate. Export them in .wso format.

✳️ Step 8: Import the edited mesh on TSR Workshop

Open Burger .wrk on TSR workshop, import your custom mesh in .wso format. Click folder with green arrow to import .wso.

After importing, you will see your custom mesh and Geostate reset to 0 for all states.

✳️ Step 9: Create Geostates on TSR Workshop, Export to Package

If you click Geostate row, the custom mesh disappears. Because the face is 0. Click on ... dots on the right side of Geostate to open Face Selector. Face Selector is to create Geostates working, Full, Half, Empty. The mesh suddenly appears with grey colour.

Left click to give colour to the face. Colouring faces based on Geostate. Be careful because the mesh is all joined into one. When give colour to Full state, do not give colour to Half state.

0x95A36FFE for the Full State

⚠️Warning! This is the trickiest part of creating Geostates: Texturing the Geostate. Cannot undo. If you wrongly click and want to undo, you have to restart from zero again. If you feel the texture is alright, then save it. You can start from checkpoint from last save if you wrongly clicked. Cancel then load the save to restart. ⚠️

Click 'n pick to click the colour one by one. Basic Square: Drag cursor to give colour in big area. Shift + Left Click: Delete 1 face. Click "Clear" to delete all the colour in one click.

Rotate the camera to make sure all part of expected geostates are textured.

Give colour to other GeoStates.

0x8A6C4E39 for the Half State (half eaten)

0x4DB2D3D2 for the Empty State (crumbs)

After you are done with the texturing GeoStates, export to package. Edit > Project contents, Export> To .package

✳️Step 10: Export MODL filefrom Package saved from TSR Workshop

Save the package with name "SpringRolls_TSRW"

Open s3pe, import package that you saved from TSR Workshop. "SpringRolls_TSRW"

Export MODL, save.

✳️Step 11. Finalizing in s3pe & Replacing the Original MODL with Edited MODL & Correcting the TGI (Type, Group, Instance) Code As Same As Default Code

Open original package you cloned on s3pe "Your Username]_AmericanEggRollsEA"

I saved the package with different name to"[Your username]_SpringRollsDefaultReplacement." to make it modified package, while leaving AmericanEggRollsEA package as backup original base, just in case I need original file.

Replace "FoodEatEggRolls" MODL that you saved from Step 10: from SpringRolls_TSRW

Check if all resource code (Type, Group, Instance) are the same as the original. Check the resource codes inside TGI Block List Editor, are they as same as inside TGI Block List Editor in original package.

You can see the resource codes are different from original FoodEatEggRolls MODL codes you copy pasted to notepad. Delete MLOD, change the codes (Type, Group, Instance) with the original FoodEatEggRolls MODL codes on Notepad. Use "Add" to add one row, Delete to erase one row. After you are done, Save and Commit.

Replace textures with your custom texture in .dds format.

Save package.

Test the package in game.

Wait until your Sims finish all their GeoStates, are the GeoStates working properly.

The geostates are working properly except at the Half Eaten state.

All states are combined into one and the plate colour are having spring rolls texture... 😱

Don't panic. Your bone assignment is alright. Copying same codes on Data Resorce and TGI Block List Editor are working properly too.

What causing the Half Eaten state is not working is:

The "Half Eaten" geostate code you are cloning from Burger mesh is not the same as code from geostate of FoodEatEggRolls.

Burger= 0x8A6C4E39

FoodEatEggRolls= 0xD8918A76

✳️Step 12. Correcting one GeoState that doesn't work because using EA's Burger mesh

Your main task here is using Default EA's Half Eaten state code to override your custom mesh Half Eaten state code.

Data Grid > ChunkEntries> [1] ChunkEntries > RCOL Block > Meshes > (on Tab [0] Mesh) > GeometryStates (then click ... Dots on the right side) > [1] GeometryStates

Second row is [1] GeometryStates, indicates it is "Half Eaten" state.

[1] GeometryStates > Name

Delete the code 0x8A6C4E39, replaced the code of the Burger with 0xD8918A76 from FoodEatEggRolls.

Click Done. You will go back to Tab [0] [1] Mesh and Geometry States

Don't forget to correcting the code for Plate as well. Plate is in the Tab [1] Mesh. Click [...] Dots on Geometry States once again, it will bring you to Geometry States for Plate.

Repeat the step as you did for the Food State: On Row [1] GeometryStates > Name, Delete the code 0x8A6C4E39, replaced the code of the Burger with 0xD8918A76 from FoodEatEggRolls.

After you are done, click OK > OK > OK > Commit > Save the .package.

Test your package in your game again.

Half Eaten state should be working by now.

✳️Step 13. Replacing the Original "Cook & Serve" MODL with Edited "Cook & Serve" MODL & Correcting the TGI (Type, Group, Instance) Code

Create custom mesh & texture for Cook & Serve, export to TSRW, then export to MODL like Eat state before.

⚠️ Pay attention because this step is very important, otherwise the Custom Food will turn black/disappear, doesn't work in the game.

Repeat Step 11: Replace the MODL for Cook & Serve state.

If you see default TGI code you copied from "foodCookEggRolls" there are only 3 lines.

_IMG 0x00B2D882 0x08000000 0x6F93B613E7C91FD0 _IMG 0x00B2D882 0x08000000 0x6F93B613E7C91FD0 _IMG 0x00B2D882 0x00000000 0xA4D80FB45AE9066B

If you want the Cook state working in the game, you should use default TGI code of Serve you copied from "foodServeEggRolls"

_IMG 0x00B2D882 0x08000000 0x6F93B613E7C91FD0 _IMG 0x00B2D882 0x08000000 0x6F93B613E7C91FD0 _IMG 0x00B2D882 0x08000000 0x0E3D40D33CC70324 _IMG 0x00B2D882 0x08000000 0x6F93B613E7C91FD0 _IMG 0x00B2D882 0x08000000 0x6F93B613E7C91FD0 _IMG 0x00B2D882 0x00000000 0xA4D80FB45AE9066B _IMG 0x00B2D882 0x08000000 0x6F93B613E7C91FD0

instead of foodCookEggRolls, otherwise the Cooked food will turn to Black colour in the game.

Repeat Step 11: Copy all the TGI codes you copied from "foodServeEggRolls" for Cook and Serve.

Commit, Save.

✳️Step 15. Check the Geostates for Cook & Serve

Check the Geostates for Cook & Serve.

Cook & Serve Geostates are working using Burger Geostates.

0x95A36FFE 0x8A6C4E39 0x4DB2D3D2 0x35B26CCB

Leave the Geometry states, no need to change to default EA Egg Rolls (otherwise your mesh will disappear or black).

After you are done, click OK, commit, save the .package as usual.

✳️Step 16. Test the CC in the game.

If your Custom Food works well in the game: Full, Half, Empty Geostates are working without showing weird texture or black or disappear, then congratulations! Enjoy and have fun with your custom food default replacement mod👍
