Right, so Sami removed the Skin you can find in villages with Wooden Canteen instead, because it didn't fit with the Finnish era. This mod is for people who disagree with that(I mean, a Skin is as simple as tying leather with tying equipment, right?).
Granted, I have zero idea if leather is waterproof off the bat. Realistically wise.
I play in imperial, so here is the weightage to compare with what Sami added.
Empty
130g skin
0.5kg canteen
Filled with water
2.4kg skin
2.7kg canteen
You get back the default Skin that used to be in the game, with the same weight values and so on.
The recipe is 130g of leather and 0.3kg of tying equipment. Its in the Utility menu.
Installation:
Just paste into the UnReal world folder after unzipping.
Regardless of it being in steam or free version, it should be in
D:\SteamLibrary\steamapps\common\UnRealWorld
Ignore the steam part. Just put diy_Skin.txt in UnRealWorld folder.
