Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Also the standard way is to use a 2dscenecapturecomponent which then renders to a material will give you a birds eye view of your terrain. Thats how th eUMG minimap on the marketplace does it but its no where near ETS2 thats heavy custom code/custom engine there.

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 https://wiki.unrealengine.com/UMG_Mini-Map . 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.

Heres some tuts https://www.reddit.com/r/unrealengine/comments/2n6wjm/how_to_create_a_2d_mini_map_using_ue45_not_the/ - using a panning node with a masked material to create a moving minimap https://forums.unrealengine.com/showthread.php?27474-How-to-create-a-mini-map - big duscission on a umg bp MM
