any way to set reparing requirement ressources

hey are there anyway to set reparing requirement as i have wepon with attachment BP that require the attachment and the original weapon to be craftet and i dont want that people are needing a new attachment and weapon for repairng it

Weapons and attachments remain separate items, even after being combined into one weapon. And repair costs are based on items, so there is no way repairs could require a finished attachment.
Unless you specifically made it that way, in which case, don’t and just copy how the game handles attachments.
Not sure there’s an actual way to edit repair costs, as the only option for them is to define how much of crafting costs they are.

is the only way you can make multiple attachments thats by making a new BP that contains thoose attachments but i might think reparing cost is something that can be done from the graph
