Well, I guess you're right... I was waiting for any Information but didn't ask.. I'm using 2017.2 (and 2017.1 at that time) and unity simply crashed with environment gator. The project folder is about 120gb and I have no idea why it crashes, it seems to have a conflict with something in my project folder, a clean install works so I was hoping for someone else to have this problem so he could report it. General feedback: there were shadow issues if the cloud object had shadows enabled (in 5.x, not 6), because of the scale of the object. Maybe it would be beneficial to have a shader-driven camera background instead.
