How can I make the mod compatible with a truck mod?
To make the Realistic Truck Physics mod compatible with the truck mod you use, follow these steps to create a custom add-on:

1.Locate Truck Mod Files
Navigate to the directory of the truck mod you use and find def/vehicle/truck/**truck_name**/chassis .

2.Copy the chassis folder from the truck mod files.

3.Create New Folder
Go to your Euro Truck Simulator 2 mod directory and create a new folder for your add-on.

4.Paste Chassis Folder
Inside the new folder, replicate the directory structure of the truck mod you use. Create a folder named **truck_name** and paste the copied chassis folder into it.

5.Prepare Chassis Files
Open the chassis folder you just pasted. You should see files with the extension .sii. Delete the sound.sui file from this folder.

6.Edit Chassis Files
– Open each .sii file within the chassis folder using a text editor.
– Remove all lines starting with residual_travel[].

7.Add Support for Realistic Truck Physics Mod
Check the chassis type from the info[] section of each .sii file.
Based on the chassis type, add the appropriate line of code to an empty line just before the closing } character:

*For a 4× chassis file, add:
@include "/def/vehicle/realistic_physics_ch_4x.sui"
 
*For a 6× chassis file, add:
@include "/def/vehicle/realistic_physics_ch_6x.sui"
 
*For an 8× chassis file, add:
@include "/def/vehicle/realistic_physics_ch_8x.sui"
 
*For a 10× chassis file, add:
@include "/def/vehicle/realistic_physics_ch_10x.sui"
Example for an 8x chassis:

8.Save Changes
After editing, save all .sii files.

9.Finalize Your Add-On
Leave the folder you created as-is. There is no need to compress it into a ZIP or SCS archive.

10.Sort Your Mods
Open the Mod Manager and arrange your mods according to the required mod order.

That is all. Enjoy realistic truck physics in your game!
