One widespread mistake that beginners in Away3D make is with the assets preloading routine. As a matter of fact, in many cases, one can see a total lack of preloading process that causes the scene content parts to appear suddenly without any logical order. Another well known issue is sequential loading of multiple objects. When we load a big amount of external assets, it is crucial to establish full monitoring of the loading process. In scenarios where there are multiple server calls and there is strong assets inter-dependency, loading errors may happen, and if you have no mechanism to get out of this gracefully, all your applications can crash even before they have initiated.
