Just translating message... Hello With the "Sandbox" tool I used the "from scratch" tool and then "shaped" my terrain. @unknownuser said: Hello With the "Sandbox" tool I used the "from scratch" tool and then "shaped" my terrain. I would now like to project a path on this land to fill the area of the path with another texture. When I used "From scratch" my land is in the form of a grid, and the stops therefore create multiple faces. So it is very complex to fill each face. If I had used the tool "From the contours" I would have only had the stops of the projected drawing and therefore the faces would have been curved but unified. I wish I could get the same result "from scratch". is that possible? Thank you for your answers.
