The unigine (2.2.1 linux Sim src) editor and projects always crash on startup. This happens both when launching them from command line and from the SDK Browser, both for existing and newly created empty projects. I have tested on two different machines with different linux distributions (OpenSUSE Leap 42.1 and CentOS 7), it happens on both. Both of them have working NVidia drivers installed. The problem also occurs with the Valley Benchmark demo too. I send attached the console output generated when running from command line, there is not much to work on in there, just a "Received signal SIGSEGV, invalid memory reference" at the end. (EDIT) Everything works fine in 2.2 in both machines. The issue is only in 2.2.1 log.txt

Hi there I'm migrating our application to Version 2.2.1. And facing some problems in the newer approach to render custom made frustums. We used the method renderViewport and passed different projection and modelview matrices to adjust the frustum to the players position in front of the screen. Now, I see that you removed this call and create some new classes, such as WidgetSpriteViewport. I don't see right now how to start to get our old functionality back. Could you please give me a hint, how to start? Kind regards, Renato
