REX Skin Pack

By Rodanius · Version 0.2.1

Seven independently selectable cosmetic skins for REX. No Eclipse progression is required. REX's native skills, damage, animation controller and effect assets are retained.

Included skins

• Prickly Customer — cactus and mechanical tripod.
• Snap Trap — flytrap jaws, visible roots in a glass jar and a seed launcher.
• Pineapple — golden rind, green crown and three articulated legs.
• Aquarium Keeper — a glass aquarium with an octopus at the controls.
• Radio Silence — vintage radio, dish antenna, vacuum tubes and horn launcher.
• Office Plant — a copier with trailing foliage, roots and a cartridge launcher.
• Spin Doctor — vinyl-record head, twin turntables, mixer and subwoofer launcher.

Installation and updating

Install REX Skin Pack through a Thunderstore-compatible mod manager with its listed dependencies. Select an unlocked REX and choose the skin under Appearance.

This update includes Pineapple and cactus in the same pack. Disable the standalone Pineapple REX package and other older packages containing these same skins. Keep one copy of Rodanius Skin Runtime. Do not enable the discontinued combined Eclipse Skins collection alongside the survivor packs. Other survivor packs can be used together.

For manual installation, extract the ZIP into the profile root with the game closed, keeping BepInEx/plugins/EclipseREXCollection/ and its assets together. The pack does not unlock the survivor. To uninstall, remove only that plugin folder; preserve other mods and save data.

Validation and reporting

The models use source-specific cosmetic rig adapters that read REX's evaluated bones. Geometry, textures, source/build consistency and recorded offline motion are checked separately from native gameplay. The accepted cactus and Pineapple model/texture payloads are preserved. The five new models use outside cosmetic weapon mounts and matching primary muzzle flashes; native projectile aiming stays unchanged. Spin Doctor’s speaker is fixed to its booth bracket to keep its cone clear during movement.

Native Windows testing of this combined update remains pending: shader appearance, controller transitions, terrain IK, skin switching, respawn, items, all loadouts and multiplayer. Offline pose previews are not gameplay footage. A synthetic sprint-entry pose shows a Spin Doctor leg overlapping a turntable; whether this occurs with the native Animator transition remains unverified. Include sprint entry/exit in the first playtest. Use matching pack and dependency versions across multiplayer peers for initial testing.

If a skin is missing or behaves incorrectly, include the package version, selected skin, loadout, reproduction steps and BepInEx/LogOutput.log. Check for duplicate enabled skin packages first.

0.2.1 rendering correction

Corrects the frame-only appearance affecting the five new multi-material skins. Each material section now uses its own renderer registered with the native CharacterModel material system, so native material refreshes retain the plant/body, roots, glass and other sections. Meshes, textures, skin identities and rig calibration are unchanged. The reported failure is matched to the native material update path; confirmation in a new Windows run remains pending.
