Classification of Mesh

Hi Community,

Im having great issues with classifying my mesh. I have segmented the exterior of a building, masks for windows, doors, walls, roofs of a building. I have also Succesfully made it so RealityScan classified these masks and I can see the colours of my masks on my Mesh, each for each class.

However when I export the file, and use it in my webapplication to filter the viewer to show these Vertex colours, nothing shows, there seems to be a loss of data stored in the mesh files and mixed with the texture colour data. Where is the metadata inside the GLB? Am I doing something wrong with my exports? Am I missing a step here?

Thank you
