As the title tells, i have an issue with weapon parts. I've made copy from vanilla Pistol, SilencedPistol. I have LUA for reloading and everything else's working perfectly except when i want to add same vanilla weapon parts for the SilencedPistol, i never get the upgrade option. Codes: item RedDot { Type = WeaponPart, DisplayName = Red Dot, Icon = RedDot, Weight = 0.2, WeightModifier = 0.2, AimingTimeModifier = 5, MountOn = Pistol; SilencedPistol, PartType = Scope, Tooltip = Tooltip_RedDot, } item Laser { Type = WeaponPart, DisplayName = Laser, Icon = HandgunLaser, Weight = 0.2, WeightModifier = 0.2, HitChanceModifier = 5, MountOn = Pistol; SilencedPistol, PartType = Canon, Tooltip = Tooltip_Laser, } item IronSight { Type = WeaponPart, DisplayName = Iron Sight, Icon = ScopeIronSight, Weight = 0.1, WeightModifier = 0.1, MaxRangeModifier = 3, MountOn = HuntingRifle; VarmintRifle; Pistol; SilencedPistol, PartType = Scope, Tooltip = Tooltip_IronSight, }So these are the vanilla weapon parts i want to add as upgrade parts for my modded SilencedPistol just like the vanilla Pistol has them. I'am able to create whole new weapon parts which can be upgraded for the mod pistol, so how i break this lock so i can get the vanilla modifiers for modded weapon?
