I'd be careful of making assumptions about 3.5 - remember it is still in beta.
That aside, the lack of a keyword to me indicates that the 3.5 is probably

I've also considered a similiar thing - my approach was slightly different. Just
use a gradient pattern on the iso, having scaled it to go from y=0 to y=1. No
lights and ambient 1, then place the camera directly above. This should result
