We’ll ETS2’s minimap will not be easy to re-create and I doubt if it can be done in blueprints, especially an entire continent.
The general idea behind a starer mini map is to place a camera in your level and then get its view though a render target and display it in a widget like this
. An ETS2 style you’d be generating some sort of 3d widget, displaying a mesh maybe, a really crazy complicated material, or else some heavy c++ code to turn road markers into debug lines (your best bet really): a constant set of loops that looks for invisible actors placed every 500m on the highways that draws red debug lines, every 750m on sideroads to draw yellow skinny lines and then of course the checks and loops for when your on a job and missed a turn etc.
Not easy!
I’ve been thinking about how to design a similar map system to ETS2 in Unity for 2 years and havnt found a perfect answer.
