I made a hair particle system and set the Dupli Group to a group of 3 objects. Each of the 3 objects has:
it's origin set to be touching the XY plane (on layer 2)
it's Scale applied to 1 and it's Rotation applied to 0
I am trying to get each of the objects to sit directly on top of the ground, but instead, they are centered in the plane, half above the plane and half below the plane:
What am I doing wrong? Here is my blend file.
