To import static meshes for building pieces, do the following:

[Step One:] create a folder with the name of the thing you are replacing.

For example, to replace the wooden chest meshes, create a subfolder in BepInEx\plugins\CustomMeshes called: piece_chest_wood

[Step Two:] create a subfolder for each of the states of the building piece: New, Worn, Broken

So now you should have three folders:

BepInEx\plugins\CustomMeshes\piece_chest_wood\New
BepInEx\plugins\CustomMeshes\piece_chest_wood\Worn
BepInEx\plugins\CustomMeshes\piece_chest_wood\Broken

Step Three: put fbx or obj files corresponding to each MeshFilter name into that folder, e.g.:

woodchest.fbx woodchesttop_closed.fbx

To import static meshes for items, you need the item name, the renderer object name, and either the mesh filter name or the skinned mesh renderer name, depending on the item. You can find these by turning on debug in the config file and looking at the messages when the item spawns, e.g.:

CustomMeshes got mesh filter item name: HelmetPadded, obj: HelmetPadded, mf: default

CustomMeshes got skinned mesh renderer, item name: HelmetPadded, obj: attach_skin, smr: ChainLinkVisor

You then create a file with the following folder structure:

• BepInEx\plugins\CustomMeshes<ItemName><ObjectName><MeshFilterName>.obj

and/or

• BepInEx\plugins\CustomMeshes<ItemName><ObjectName><SkinnedMeshRenderer>.obj

For example:

• BepInEx\plugins\CustomMeshes\HelmetPadded\HelmetPadded\default.obj

or

• BepInEx\plugins\CustomMeshes\HelmetPadded\attach_skin\ChainLinkVisor.obj

To import player meshes, you need to create an AssetBundle with a body object in it. Please don't ask me how to do that, I have no clue. You can ask people working on it in my discord server if you know something about Unity.

Step One: create a folder called player with a subfolder called model in the CustomMeshes folder. So now you have:

BepInEx\plugins\CustomMeshes\player\model

Step Two: put the asset bundle you created in the subfolder, naming it 0 for male and 1 for female (make sure it has no file extension).
