Want to set up kits for Scrap, economics and Rewards or combinations of these.
is it possible ?

Charging in-game currency for Kits

When you are editing a kit you can set a Cost price. Kit's that have a cost price assigned to them will charge the player that amount of currency to purchase. If the player does not have enough of that currency they can not claim the kit

Kit purchasing supports 3 currency types; Scrap, Server Rewards (RP) and Economics.

You can change which currency system you would like to use in the config

Yes but trying to do all 3, such as 20 scrap, 30 reward points, 10 economics . This does not say how to do that

eracet

Purchase Cost - Lets you set a price for the kit that players must pay before they can claim it

At a guess i think you would put it where it says cost ?
