How do you bend a 2d texture in 3d?,How do you bend a 2D object in 3D?

I am trying to make a game that is played on a 2d plane that bends in 3d to offer more variety for level design. An example would be the 2d sections in Super Mario Odyssey, which often curve their 2d plane to change their 3d direction. The problem is that their are no ways I could find that allow a 2d sprite to be bent on a 3d curve. If anybody knows a solution to this, the help would be much appreciated! Thank You!
