Sadly I am working with a hex editor before applying this to code logic - so this is what I basically do:
I look for text, literally, for the ores, it was "Ore" (caps matter) and when I find a mesh definition that looks something like
I replace the first slash with a hex 0x00 which is a string-end-marker code wise, so the game tries to access the mesh for "" which does not exist and, I assume and hope, it will skip determination and not load the item because it cannot find a mesh to display it.
I am fairly certain that this works for small use cases, and if you want to do the same, it MIGHT be doable to simply change letters in the mesh definition "MyAsset" -> "MyBsset" - if you do not use a hex editor, good luck xD and make sure you do not add or remove any characters [the total count of where you edit has to be the same!!] because the way the savegame works is that it has indicators all over the place "how long" the following text and other content is planned to be - so if you add or remove characters the savegame will probably fail to load :D
If you have issues implementing this, just hit me up and I can add "remove all logs and wood" to my fixer :)
