I have been exporting .skp files to .dae files so that I am able to import them into Unity. The colors generally work out well, however, most of the time the mesh is unable to be used as a single mesh, but only as small parts of the same mesh. This does not occur on all the models I try, but only about 60-70% of them. I have tried grouping them and making them into a component in SketchUp.
Has anyone had a similar problem or know a solution to this?
