Hair Paricle System not rendering properly on plane My scene involves a plane that has several modifiers:


Subdivide, set to six.
Array, set to -1 Y axis
Array, set to +1 X axis
Displace with a basic cloud texture


I tried following Andrew Price's tutorial on realistic grass, by adding the default hair particle system to the plane and setting the render to a group of grass, but the grass only appears in a small space in the render. What am I doing wrong?
Make sure the use modifier stack checkbox is checked in the Emission section of Particle settings.
