2026-01-20: OSA has been updated for U242. Big thanks to [6IX] for the fixes.

Some things might still not be working correctly after U242, will slowly fix everything.

Note: Optional Skin Attachments is NOT compatible with Super Duper Skin Swapper. Legendary skin support is already built into Super Duper Skin Swapper.

This mod allows you to choose which attachments to use when applying weapon skins and provides improved support for legendary skins. Key features and options:

• Choose Skin Attachments: Replaces the apply/remove skin confirmation dialog with a menu that allows you to choose which attachments to use. Attachments that are part of the skin will show up as "Available" to use while the skin is applied (as is the case in the base game).
• Autobuy Missing Mods: Automatically buy missing weapon attachments using Continental coins when you choose to keep your current attachments.
• Autobuy Threshold: Do not let Continental coins drop below this threshold when autobuying (range 0 to 200).
• Prefer Shotgun Pack Buckshot: Give the Gage Shotgun Pack 000 Buckshot priority when applying skins. When skins are applied or removed, the free 000 Buckshot will be replaced by the Gage Shotgun Pack 000 Buckshot if you own the Gage Shotgun Pack DLC.
• Save Mods On Missing Skins: Try to keep attachments when skins are removed from Steam inventory.
• Choose Attachments in Previews: Enable dialog menu for choosing attachments when previewing weapon skins.
• Rename Legendary Skins: Allow legendary skins to be renamed.
• Customize Legendary Skins: Allow legendary skins to be unlocked so that they can be customized.
• Remove Legendary Mod Stats: Remove stats from legendary weapon attachments.
• Show Legendary Mods: Show legendary weapon attachments in weapon customization menu so that they can be selected. Can be set to only show mods from owned legendary skins.
