1. You must first triangulate your mesh (manually or via the modifier). 1. You must first triangulate your mesh (manually or via the modifier).
* Your geometry must not exceed 460 triangles, or it won't load properly.
2. When your model is ready, you can then vertex paint it. If you don't, the vertices colors will default to white. 2. When your model is ready, you can then vertex paint it. If you don't, the vertices colors will default to white.
* If you modify your geometry *after* vertex painting, the plugin will faile to export the mesh. This is because the vertex color data is set to 0 each time you modify your geometry. * If you modify your geometry *after* vertex painting, the plugin will faile to export the mesh.
