\n(screenshot with Quad mesh placed on top of Plane with raycast hit.point)<\/p>\n

If you want to use Raycast hit.point to place quad on a flat surface, it will most likely create Z fighting issue..
\nYou could add position offset by hit.point+Vector3(0,0.1f,0),
\nOr use modified shader to add offset:<\/p>\n
