The game is packaged as for release so all assets will be packed and the project can't be edited as a raw project. Releasing that would not be feasible (150gb + in size currently) and several assets I use have licenses stipulating they need to be packaged when included in a game.
However I do very much want to both encourage and support modding of the game. I haven't found any great tools to enable that in unreal yet and I have no experience modding unreal games myself.
I do know there are tools that can unpack packed unreal assets but I haven't tried them. Will try to figure out good ways of doing this as I further develop the game.
Very much appreciate both your interest and offer to help out! Keeps me motivated and push me to do better.
Feel free to drop in on discord, I always love good discussion on improvements or features!
