do i just add everthing to the scripts folder? models and all?
Look in your shiplist and you will see a file path for every ship entry. This file path leads to the model used by that ship. Usually the filepath is something like Models/LDD/LDD.mod, which would mean that the shop uses the ldd model in the ldd folder, which is itself in the model folder. (The model folder is in the assets folder in your game.)
Put your models wherever that file path says to put them. The assets folder is assumed to be the start of your path, so if you want you could create a new folder called, for example, MyCoolModels. Then, if you created a new ship in your shiplist called CoolShip, you would have its filepath entry look something like:
MyCoolModels/CoolShip/CoolShip.mod
Make sense?
