Hi!
If you can make it so that unique names can be given to items, then you will be a huge genus :)
Custom item name
They already can, they are just not displayed in the shop UI.
And will something come of it? :)
How can it be called anyway?
If it works, I will gladly give you a little financial support!
Items in Rust have a property called name, which is normally null for most vanilla items (causing the Rust client to decide which name to display according to the user's language), but that property can be set by plugins to customize the item display name. Many plugins do this for special items. When you save the vending machine loadout, this plugin will recognize custom display names on items that were in the edit container, and will save those names in the data file. When a player purchases one of those items, it will have that custom display name.
The FAQ in the plugin documentation mentions this limitation, and mentions that I plan to add support for viewing the custom item names in the shop UI in the future, but I am currently busy with several other projects.
Alright, thanks for the info and patience in the future! :)
