Is it possible to have some Levels/Scenes in order and some random? For Example lets say that I have 20 levels and I want Start,1,2,3 to be in order than I want to have 4,5,6,7,8 to be random than 9,10,11,12,13,14 to be in order, etc.
Yes, you can do that based on "distance". If you click on the level, on the right hand side there is the advance properties where you can define when a level starts and stops. -1 is "forever". If more than one active at the same time then levels appears randomly. Also next to the level selection there is a tiny triangle, click on that and then you can adjust the start and stop by those lines. Drag them with the little dots.
