SADmodelfix
Fixes broken mod models at runtime: convex MeshColliders, spawn bounds, center of mass, volumeType. Also suppresses PhotonView IPunObservable spam and LocalizedString empty-table errors.
About this mod Author’s original text
SADmodelfix
A BepInEx plugin for R.E.P.O. that automatically fixes common issues in community mods — broken physics colliders, wrong spawn bounds, incorrect center of mass, and misclassified object sizes — all at runtime, without touching the original mod files.
What it fixes
| Fix | What it does |
|-----|-------------|
| MeshCollider | Enables convex mode on non-convex MeshColliders so objects fall and rotate with the correct shape (not like invisible cubes) |
| RoomVolumeCheck | Recalculates the spawn AABB pivot and size so objects actually spawn in rooms instead of clipping through walls or floors |
| Center of Mass | Moves Rigidbody.centerOfMass to the geometric center of all colliders so objects don't spin wildly when grabbed |
| VolumeType | Auto-classifies Tiny / Small / Medium / Big / Wide / Tall / VeryTall based on real mesh bounds so objects end up in the correct loot pool |
| Hierarchy Check | Detects mesh renderers incorrectly placed on the prefab root (experimental, off by default) |
| PhotonView Fix | Removes non-IPunObservable components from PhotonView.ObservedComponents — stops thousands of Photon error spam lines per session (e.g. ChargingStation, Minecraft items) |
| Localization Fix | Suppresses ArgumentException: Empty Table Reference spam from mods that register items with an empty LocalizedString table |
| SillyValuables Fix | Preloader patcher that rewrites SillyValuables.dll on disk to fix MissingMethodException: void.Sound.PlayLoop(bool,single,single,single) spam — grenade/throw sounds in SillyValuables now work correctly |
Installation
Install Mod Manager or Gale — no manual steps required.
Manual: drop REPOModelFixer.dll into BepInEx/plugins/REPOModelFixer.

Install & use Install: BepInEx plugin
- The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
- Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
- Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
- Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.
Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.
Install these first, or the mod will not work:
