Abstract: A method, computer system, and a computer program product for projecting a 3D model defined by x, y, z coordinates onto the surface of a 2D image defined by u, v coordinates is provided. The present invention may include receiving a 3D model having a plurality of polygons, wherein certain edges are marked as seams. The present invention may include receiving input from a user, wherein the input comprises painting one or more parts of the 3D model in different colors, wherein the colors correspond with a weight of the area painted. The present invention may include unwrapping, by a processor, a 2D texture from the 3D model using a projection algorithm. The present invention may include generating a rectangular boundary around each island. The present invention may include scaling each island according to a gradient score.
