Hi
Your minimap is a SUPERRRR AAA minimap.
I’m able to use thin edge, and it works perfectly.
But to achieve this all the elements touching at the edge must be changed to ‘Arrows’ with same texture used in the points. And inside the minimap widget blueprint there a function called ‘Intersect with Edge’, I changed the value 2 in division for circle radius to 1.7, to coincide with the same exact time and place that arrow is transformed into points, vice versa. and it worked perfectly.
About Indoors
Most often, both images in the minimap, indoor and outdoor are schematic images captured in the first instance by scenecapture2d, but then are replaced or combined with images processed in photoshop. After scene be captured by scenecapture2d, conbined or replaced, you can to delete the minimap’s camera. This minimap works with both, scenecapture2d and photoshoped image.
