Grouping shapes by their orientation in Substance Designer

Most of the time we find ourselves using downloaded PBR materials from sources like Megascans or others. If we can get a clean mask, then we could parameterize the texture in order to further enhance it. This is an algorithm that is grouping shapes based on their similar orientation. We can then get a mask for specific groups. After that, we can use Floodfill to gradient in order to create properly oriented UVs for the shapes in that group. Finally, we can add specific details (for example, additional grooves - properly oriented - on some selected bricks).
