Draw Areas at runtime on top of terrain
i'm designing a game that user can Draw an area on top of terrain and shares it.
so my thought is it could be done with Drawing Polygons on top of terrain(at runtime) and polygon change color of terrain it covers. but how?
or drawing lines on top of terrain ( Vectrosity ) but it need to be closed shape so it can be highlighted.
does any body how to implement this? for short : i want this with my Custom map : https://www.assetstore.unity3d.com/en/#!/content/55121 Thanks.
