Custom Blueprint Assets Pawns, Maps, Etc. - KH3-Modding-Org/OpenKH3Modding GitHub Wiki
This will be a quick tutorial for creating custom assets from super complicated original assets without needing to fully recreate the asset in the editor.
Find and copy the asset you want to duplicate and add custom code to.
You can do this after cooking as well, but copy/paste the asset into the folder you're going to pak.
Rename it to anything other than its original name.
Open the asset in uassetgui and find any references to self.
Rename to the same as the renamed asset.
Go to view->refresh nodes to see the changes.
Save the asset.
Now, open TresGame in UE.
