Well I think this would come in handy for those who want to do animations that take place in a room or on a street. We have seen(and I have done) many scenes where there is a flat surface.

I don't personally have any use for such an ability though. Plus I know how long a high quality render single frame picture takes. I can only imaging how long an animation in Vue would be. :)

Personally I am only using Vue for it's single image, but hey, I am sure there is a decent amount of those who could find a use for this. :)
