Here is a low poly style landscaping with this style of coding, just a few tweaks to do on the vertice colourings.

Added 2 functions
Function CreateObjectFromMeshWithColor(m ref as mesh) - this will build a mesh with colours
Function CreateObjectFromMeshWithUVTexturing(m ref as mesh) - this will build the mesh with texture an UV capabilities
Going to working on the rolling mapping it now
Long way to go yet
