Hi Schizo,
you can see the location of assets by clicking on a resource in the
![[Linked Image]](https://docs.larian.game/File:ContentBrowser_Icon.png)
content browser and checking the "source file" property there.
The correct way to mod these is by putting your customized .gr2 file in your own mod (e.g. Data/Public/ShizosMod/Assets/Characters/Lizards/Lizards_Male/SHIZO_Female_Skeleton_A_Body_A.gr2), then opening that mod in the editor and overriding the resource you want to change by changing the source file property on it to your custom model.
Hope this helps!
