I encountered a problem populating on an object. An integral part of the (separated ground) object just didn't get any instances. And not because the normal of that particular strip of polys was upside down, or the population size was inadequate.
Has anyone encountered this, and what might be the problem?
I had to resort to using a floating card in that particular (yellow circled) area, to grow an extra pop of flowers on, so it's solved, but still puzzling.
