Cannot get unborn particles to render

Hello,

I have been trying to use particles to cover a landscape scene with trees. I was following the tutorial for creating an island environment on Blender Cookie, and I followed the instructions perfectly. I am running version 2.67 of Blender however, while the tutorial was made using 2.63. Does anyone know if there are additional steps I need to take to get unborn particles to render properly?

Thanks.

Set the particle emit start and end frame both to 1 so all the particles are visible

Hmm, I tried that. It got me to be able to see the particles in the viewport, but they still didn’t render. I was following this tutorial:

Blend file ?

Oh, never mind. The original solution did end up working. Thanks for that. Still, I wonder why it won’t render unborn particles when I have that box checked.
