Development Programming & Scripting Blueprint

Anyone please help! I am newbee in unreal engine, I have a project to make a simulation to change material on the wall of the house, for my thesis. I wanna save every wall that the material has been changed. I have not found the way to save it :frowning: your response will be meaningful to me. (sorry for bad grammar)

If you want to change the textures on your walls in runtime, you will need to set some “material” variable for each wall.
You will then want to save these variables in an object to get them back after quitting the game.
If I’m right, the object you search for is the game instance

here’s a video on how to use it : HTF do I? Use the GameInstance Object in Unreal Engine 4 - YouTube
You can save array of variable in them :slight_smile:

Actually the object to “save” things to the disk is a “SaveGame” object.
Game Instance will reset everything after your app close.

Your assurance gives me doubt but I use only gameInstance and no savegame and my game keeps the settings for keybinding and all even after a restart…
