You want Realism? - Then your inventory would be no more than 5 items (mainly dry meat for travel in a pouch on your side) - can't store extra food / quest items as well on your person. Your horse can carry maybe 15 items but only if you have saddle bags. Most of that will be water.

There ya go, realistic capacity. Good luck.

I love realism, but I'm also a pack rat so, I've never used any mod that limits carrying capacity. Making a carrying capacity mod should be easy, though.

How to Create an XML File

1. Open your text editor of choice.

2, On the first line, write an XML declaration.

"<?xml version="1.0" encoding="us-ascii"?>"

3. Set your root element below the declaration.

<database xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="barbora" xsi:noNamespaceSchemaLocation="../database.xsd">

4. Add your child elements within the root element.

<rpg_params version="1">
<rpg_param rpg_param_key="BaseInventoryCapacity" rpg_param_value="30" />
</rpg_params>
</database>

5. Review your file for errors.

<?xml version="1.0" encoding="us-ascii"?>
<database xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="barbora" xsi:noNamespaceSchemaLocation="../database.xsd">
<rpg_params version="1">
<rpg_param rpg_param_key="BaseInventoryCapacity" rpg_param_value="30" />
</rpg_params>
</database>

7. Save your file with the file extension “.xml” rpg_param__weight.xml

8. Test your file by opening it in the browser window.

........................
Or you could just open any xml, delete everything and paste the above lines and save.

File structure should look like, and yeah, create the folders:

weight\Data\weight\Libs\Tables\rpg\rpg_param__weight.xml

Now go download a PAK builder from Nexus Mods, follow the instructions and build the pak, or use Winrar and make a PAK outta this part of the file structure:

weight\Libs/Tables\rpg\rpg_param__weight.xml

Cut and paste the pack back into its parent folder.

Manifest file

Open a new text file, paste the following

<?xml version="1.0" encoding="us-ascii"?>
<kcd_mod>
<info>
<name>weight</name>
<modid>weight</modid>
<modifies_level>false</modifies_level>
</info>
</kcd_mod>

Save as mod.manifest

Place manifest in mod "weight" folder, the one containing Data.

Now it's a mod that sets the base carry weight at 30.

Actalo, thanks for the info. Luckily, I've found some mods on Nexus that set your base weight lower, and even reduce the amount you gain with perks. I'm trying out several different ones now to see which hit a good sweet spot and make the game more challenging, but still playable. BlueLine makes a good point. Realism would not be enjoyable at all, let alone even playable. I'm just looking for a bit of a challenge and a limit to loot hoarding. I'm looking forward to using one of these on my first hardcore mode play through. Cheers!

Note: someone even made a mod for adding weight to Groschen and I've been using that as well. It's awesome.
