The apps always seems to take a long time to start even when simply opening an almost empty scene, is there a way to put a loading screen or logo in while loading to let the user know something is happening? It seems as if the entire app needs to be loaded in at the very beginning, as loading our heavier scene asynchronously occurs very rapidly, while initial launch takes up to a minute or two to start.
Adding support for a loading screen is definitely on our road map; I don’t think there’s a good way to do it at present/without lower level support. One thing that may be slowing the initial application load in the current version of PolySpatial is an errant call to Resources.LoadAll that is loading all resources at startup. That will be fixed in the next version.
