Hey! The player location and markers should be calculated automatically.
You should just play around until all your map is within the box. It’s best to use the ‘box size’ variable in the blueprint details (on your level) instead of scaling just in case.
If you are using your own map texture (it’s always better that way), don’t forget to press “Show Decal” until you align the textures.
I am not sure if you are having another problem. :-/
Hope you figure it out, but if you have any issues post again and I’ll do my best to help
