I think scenarios are a key feature of this program and would be glad to see any upgrades that extend there functionality further. The reporting abilities of CityEngine combined with scenarios makes it a very powerful tool.
I noted some of my comments about scenarios in another post but here they are again. The street lines and nodes can be toggled to multiple scenarios but there is some underlying problems with the way it is implemented. Let's say that I want a street segment to be available to all scenarios, and that segment is connected to another segment that is going to be based on different scenarios. When I get to the street segment where I need different scenarios and connect them back to the all scenarios segment, things don't behave quite the way I would hope. Same goes for trying to use nodes for different scenarios. Try to make a street intersection that is available to multiple scenarios and connect them with segments from individual scenarios and you'll see what I mean. Because of this, I just find it easier to copy the whole street network for each scenario.
But if this behaved more expectedly, I could save time and computer memory by working on segments of the street that would be the same for multiple scenarios all at once. And the tweaks that are made to make them look better over time would apply to them all.
On my personal CityEngine wish list, I would rate this a medium priority.
Also, I particularly like how well CityEngine is doing with its exporting capabilities! I imagine keeping up with all those programs is a hassle.
For my personal high priority item, I would really like to see a "rounded corners" or bevel ability/code. It would be even better if we could pick the faces that get beveled, either by comp selection, or maybe like a shape modeling tool. I think this would help with many different aspects of design - from softer looking buildings and edges, to easier creation of common building and parking lot shapes, and more.
