Smart materials on UVless meshes in Unity3d HDRP

Another UVless workflow experiment in unity3d. The idea was to bake different maps (curvature,AO etc.) into the mesh vertex color, and use those maps to blend between different material layers. Also all the materials use triplanar mapping (since there's no UV on the mesh). All the shots created in unity3d HDRP.
