So I am making a strategy game in UE 5 and I want players to be able to draw notes on the map (map is just a plane with a texture) like in MS paint. I also want so they can use eraser that will reveal original texture. What’s the best way to do it? I know that it can be implemented using render targets but I also heard that it can somehow be done using user widgets.
For technical reasons I am restricted to only using blueprints.
Thank you!
