I am urgin for shadows improovements since I got 3dgs, but it is always on HIGH-priority in forecast. This great looking shadows have almost every good engine and for their users it is natural to have images like this. Law maker for example have very simple system, just place a light and you have a different type of shadows to all objects. There is no need to use all those tools to acheeve simple things like GOOD shadows. No plugins, no third party programs, just import model and fantastic shadow is already there even in production stage, without compiling.
