Hello ou there,
I finally found out, how to change the skins:
You need to open Tables.pak
Then navigate to Item-Folder
Open Pickable_items.xml
There you find lines like this:
<row entity_script="" item_id="db0725ac-c0e0-41db-b7a6-2887c57df612" material="" model="weapons/swords_long/long_sword_h" owner_fading_coef="0.02" price="22037" visibility_coef="1" weight="3.133333" />
<row entity_script="" item_id="9d2561cc-892f-4527-94cc-4fa607102949" material="" model="weapons/swords_long/long_sword_j" owner_fading_coef="0.02" price="14244" visibility_coef="1" weight="3.4" />
Just compare the item_id with the names given in player_item.xml and you can exchange the Models as I did in the example with the sword of St.Georg and the Sword of Longinus.
Have fun.
