ATS to ETS 2 conversion issues.

#1 Post by WolfRamXX_CZ » 23 May 2026 06:22

Hello, Im trying to convert the ATS box trailer (specifically the 28, 45 and 53 feet dry vans) for my personal use and have all kinds of problems with them... Notably the "dangling pointer" error, which ive tried to fix for last two days without even figuring out what the core of the problem is in the first place...

Some advice on what it means/how to solve it is welcome.

Also, Im not entirely sure if its legal to convert ATS assets to ETS 2? As far as I know, if its for personal use ONLY, its fine. Correct me if Im wrong though...

The game is looking for files that are stored in "/def/vehicle/trailer_defs" and cannot load them because these particular trailer definition files are not present in ETS2.
You'll need to run the SCS Extractor Tool on the "def.scs" file from ATS to expose this directory so you can copy the required files into your mod's file structure so the game can load the vehicle properly.

I allready did that and had the files in the directory, however i had def/vehicle/trailer_defs/ats_box/*the files*. Moving the files out of the ats_box did the trick. Also fixed few more automat issues I just found.

Im now getting a lot of errors about not finding files that are 100% present. Im beginning to think it has something to do with why the trailer doesnt load any textures though :lol: The ones with /vehicle/trailer_owned/scs_box/X are obvious why they dont work- it should look for ats_box as thats what I renames all folders to to prevent clashing with basegame. Why the ones that load correct folders dont work is beyond me however...

Those "failed to init update for object" means it cannot find those files. Show us an image of the ats_box directory.

thats the /vehicle/trailer_owned/ats_box/ directory. Straight up copied from extracted base_vehicle.scs files, other then renaming scs_box to ats_box, I didnt touch anything here

That's odd, I had that exact error on a mod I'm working on and moving those exported files from Blender into my mod fixed it.

I'm not saying load it into Blender to fix it as that'd be a chore for those affected files.

Moving the textures to a non-conflicting folder isn't enough here.
You will need to update the internal file path stored inside the TOBJ files so they know where the textures are as these files contain explicit file paths in them.
You will either need a tool that can handle TOBJ files or you will need to edit them manually with a HEX editor.
If you go the HEX editor route, make sure to update the 2-digit character above the file path for the changed file path length.
The number is in hex and a full line of characters 16 is "10". So if you have 5 full lines of text for the filepath, the length will be "50".

Thats what I thought.... Honestly, its probably going to be easier for me to get them in Blender (if I can figure out which version i need for SCS tools, I allready have 3 different versions for multiple other games...) and fix the paths there. That way I at least have access to the models and can make some custom stuff for my self, not to mention I allready have expirience with it so it should be swift work there.

With that being said, thanks for the help so far, apriciate it :)

EDIT:
Nevermind, I though tobj is variant of obj, an model file. Guess not. Found a extremely usefull tool to edit the texture paths however!

EDIT 2: Electric boogaloo:
Fixed all .tobj files and potentially found the core issue of the mod: I need to edit atomat files, as they all reference scs_box too. I did not kow Notepad++ can open the .mat files...
