If I rendered a small circle moving across a plane to the heightmap used by a cube, would it look like a little lump traveling around the cube?
Well it’s a circle because it’s drawn to a 2D image. The heightmap is 2D. So if I animated a circle moving across that 2D surface, it’s possible that it would look like a lump moving around on a 3D object.
@UberGoober - yup, I agree. Also you may probably see the circle retaining size if you move the cube in the z axis as the 2D element would be fixed unless you scaled accordingly
