Once I constructed the the mesh of our track in Meshlab I needed to import the mesh into unity. Unfortunately Unity does not read per vertex colors so I a made a texture from the mesh so that it could be applied to the colorless mesh I imported to unity. However the texture I created using the per triangle parametrization method in Meshlab seems slightly inconsistent when imported into Unity so right now I'm working on smoothing out the colors more.
Note: make sure your normals are facing the correct way when you generate them in Meshlab otherwise the wrong side of the mesh will be showing
