Myriad Lite Holster

Players can draw weapons from a holster or sheathe to begin combat, or sheathe/holster weapons to withdraw from combat.

See the Commands page for holster commands.

Setup

1. Create an object to act as a wearable holster for a firearm or a sheathe for a melee weapon.
2. Drag and Drop the Myriad Lite Holster script from inventory into the holster object: ?
3. Attach the object to the desired attachment point.
4. Adjust the position and rotation.
5. Detach the object back to inventory to "save" the new default attach point.
6. Attach or wear the holster when desired.
