In 1986, the world's worst nuclear disaster occurred at the Chernobyl power station. Soviet authorities established a 30km 'Exclusion Zone' around this nuclear wasteland, but in 2006 a second explosion rocked the stricken reactor, obliterating all living things and causing the Zone's boundaries to ripple outwards. From this epicenter came waves of mutated creatures, deadly radiation, and a strange, anomalous energy. The Zone was cordoned off by the military, who would shoot on sight anyone foolish enough to brave the horrors within.

Report article RSS Feed Changing the weight limit

I didn't see many forums explaining how to change the weight limit in S.T.A.L.K.E.R.: Shadow of Chernobyl, so I thought I'd make one myself, just to help other Stalkers out there.

Basic Other.

Hello, everyone.

It's pretty simple to do what the title mentions. Just a few tweaks and then you'll be able to carry as many KGs as you want in S.T.A.L.K.E.R.: Shadow of Chernobyl.


ATTENTION: If you already have a mod installed in S.T.A.L.K.E.R., then you should have a "gamedata" folder in your game directory. If so, then skip the first three steps.

1st step - Download the .rar file from the link below:

In order to be able to change the weight limit, you must have a gamedata folder along with the "system.ltx" and "actor.ltx" files. Note that you need WinRar so you can open the folder from the link. It is free so you can download it easily.

EDIT: This stands as an alternate link for those who don't possess an account on 4shared:

2nd step - Move the "gamedata" folder.

Just move the folder found in the .rar to your S.T.A.L.K.E.R.: Shadow of Chernobyl game directory.

3rd step - Modify the "fsgame.ltx" file.

To make the game read the data from the gamedata folder, you just have to change a word in your "fsgame.ltx" file, found in your S.T.A.L.K.E.R.: Shadow of Chernobyl directory. Open it with notepad, and you should see something like this (without the quotations):

"$game_data$ = false| true|"

Just change the "false" statement into a "true" one, and it should look like this (without the quotations):

"$game_data$ = true| true|"

4th step - Start tweaking the "system.ltx" file.

Alright, now we can begin changing stuff from the "system.ltx" file. It's found in the "gamedata\config" folder. Open it with notepad then press Ctrl + F to search a word. It's easier like that, rather than searching something for yourself in the whole document. Alright, after pressing ctrl + F, write in "max_weight" (again, without the quotations). If the game isn't modded, then the "50" value should be next to that line. Well, that's the value of how much can your character carry before starting to tire. You may change it to whatever number you like. Let's say we put 100. After that, just close the file and save the changes.

5th step - Start tweaking the "actor.ltx" file.

Now there are still two changes that must be done before being able to carry as many KGs as you want. First, just open the "actor.ltx" file that can be found in the "gamedata\config\creatures" folder with notepad. Then press Ctrl + F again and search for "max_item_mass" (without the quotations). Next to that line, the "50" value should be input, if your game isn't modded. Alright, now you probably noticed the max_weight's value and the max_item_mass' value are the SAME. So you should input the SAME value to them both, otherwise it won't work. So if we put 100 to the max_weight's value, then we put 100 to the max_item_mass' value as well.

After that, search for "max_walk_weight" (without the quotations). The value next to it should be "60" if your game isn't modded, and it indicates how many KGs your character may carry before he won't be able to walk anymore. As you may have seen, this value is HIGHER than the other two values. So you should change it to a higher value too. If we input 100 to the other two, then we must put...let's say 110 to this one. Of course, you may put even 200 if you like, it's just that the number must be higher than the other two. After that, just close the file and save the changes.


And...there you go! Your character may carry a new amount of KGs. Whether it's a smaller value just to increase gaming realism or a higher one to increase fun, I hope this tutorial helped you.

Update #1 - added an alternate gamedata link for those who don't possess an account on 4shared. I apologize if some of you had to create one in order to download the file.

Sorry for the late reply, I haven't seen your comment before. This tutorial isn't outdated. You should read it carefully in order to make things work.

Download the gamedata folder, copy it to your STALKER SoC directory, then start modifying the actor.ltx and system.ltx files as described in the tutorial.. You can open them with Notepad. And for SoC to read the modified data there, you must tweak the fsgame.ltx file. Please read everything carefully and you'll succeed.

Do you have any mod installed? It's possible that data from it might've been overwritten with the gamedata folder that you downloaded from here. If you do have a mod installed, then skip three steps as the tutorial says.

You need to be logged in as an administrator. If you already are, then right click on the file and press "Properties". Then click "Edit" in the "Security" tab. Press "Users" and click the square next to "Full Control", under "Allow" section. Press OK and you're good to go.

Also check if the notepad is actually "Read-only". You can verify that in the "General" tab.

Don't click on "Add" in the security tab. Just click ONCE on the "Users" then check the "Full control" square. Press OK and you're done.

The "Users" thing should be named like this: If your PC is named, for example, "One"...then that thing should be named like this: "Users(One\Users)".

Alright, I'll need the log file to see if I can diagnose the problem. Follow the instructions bellow:

"If your game crashes or locks up, look for the log file that STALKER creates before running your game again. (STALKER overwrites the log each time you start the game.)
The saved games and logs are on the C: drive by default in the STALKER-SHOC subdirectory. In Vista and Windows 7 this subdirectory is under \Users\Public\Documents (Windows 8 is similar: \Users\Public\Public Documents) while in XP this is found in \Documents and Settings\All Users\Documents.

For Steam users, the game uses the directory assigned to $app_data_root$ in fsgame.ltx. At least it tries to do so; see the Troubleshooting FAQ if you have problems saving your changed settings or making saves.

The latest error log, called xray_<your_user_login>.log* is under STALKER-SHOC in the logs\ subdirectory, while the saved games are stored in the savedgames\ subdirectory.

*<your_user_login> is usually your name, the one you see at the top of the menu when you click on the "start" button on the taskbar in XP. If your user name is Robert, for example, then you would find a file named xray_Robert.log.

NOTE: Sometimes the .log extension is hidden because Windows already has assigned the file type to an application.

Open the log file with a text editor or viewer. At the end of that file is usually a section that starts with "FATAL ERROR" and has lines beginning with "[error]" or following "stack trace". These lines are useful in identifying most script and configuration errors."

OP: Kudos for reminding me how to do this!

Stalker SOC (CS/COP) with installed mods, may require additional editing in the gamedata files, for getting the tweak/cheat to work.

Stalker SOC with F.O.T.O.G.R.A.F. had an additional file in C:\S.T.A.L.K.E.R. - Shadow of Chernobyl\gamedata\confign
"arc_inv_weight" - where you´d have to set the value the same as in "max_item_mass"

Hm. Yeah. However... soon after posting i was reminded that some of these "interresting" Russian mods are pretty hard to edit, as the devs seem to want you to play the mod their way.
In Fotograf, post carryweight-edit, the guy will be staggering and panting instantly when attempting a sprint, so it will require further tweaking... Spent two hours last night looking into and testing the usual tweaks to no avail...

No problem, and yeah, it is kind of difficult to edit the game once mods are added. I am planning to play STALKER again but right now I'm busy with some other games :D.

Update: The devs of Fotograf did include (hide) a little something extra in the scripts.
One has to edit max_weight in "boryan67.script\" and "boryan67.script.bak" also.

OP: Sorry for the mess...

The End.
