Here is the
my screenshots

The shader used is attached.

I attached the script File, Actually, It is the same as the DottedLineExample If it works I will move to a new script to do some customize but mainly I would like to see how it works.

coords = new Vector2[2];
coords[0] = new Vector2(longitude, latitude);
coords[1] = new Vector2(longitude, latitude);

and I add it as a component to my map. But doesn't appear on the screen.

I attached screen shot

Parameters which I gave to DottedLineExample :
Size : 10,
Uv Scale : x => 2, y => 1
Material : (I created standard material with random color)

In this example, coords is Vector2 array where X is longitude and Y is latitude.

I use FindDirectionExample to create a path between two points. Inside the FindDirectionExample use OnlineMapsDrawingLine to create a single line between two points but I want to turn it into a Dotted line. I review DottedLineExample but I didn't get how to use lon/lat coords with DottedLineExample. Is there any way to create a dotted line between two points with coordinates? (lon/lat)

Thank you.
