I want to start by saying I am total fan of Outerra. I think it's awesome in every way. However, there is one change that would make it even more useful to me as an animator who has accumulated a bunch of 3D assets that are sized appropriately for other environments.
If there was a way to dynamically resize imported objects it would save me a lot of work, and it would also keep me from having to maintain multiple libraries of the same assets.
I know there is a resizing feature at the import stage, but it is much more convenient to drag a slider and watch an object grow or shrink to match its surroundings.
Having said all that, I will continue to enjoy enjoy Outerra whether or not that functionality is ever added. I'm just dreaming out loud. (It might be worth mentioning that I've gotten a number of my animator friends interested in Outerra, and the number one question they always ask me is whether or not there is a way to dynamically resize imported objects. Maybe artsy types tend to be more visual in their approach?)
