Copper SDK — or CSDK — is my plugin for Godot that acts as an "editor" for all things Copper Trader.
What you're seeing below is an early screenshot of the CSDK's Cell Editor. The Isle of Gūr is divided into 1028 cells, each with a plethora of options to tie it into the game world: setting a faction, regional wealth, primary traded good, aggression towards the player, and more.
Once a cell is opened it can be viewed in the editor and have assets placed onto it. Multiple cells can be referenced & opened at a time to build larger outposts and cities.
Cells are loaded and unloaded dynamically and have LOD meshes, so resources can be better allocated to background simulation.
The whole map can be viewed with every cell loaded, too. Below you can see a cell being loaded and edited.
As you can see in image one, there's a plethora of features in the CSDK to assist in the easy building and managing of game content. It's a pretty nifty thing to have when you're the kind of person who just wants to make things!
