I have a blender project setup, it is simply a building and a pond that are sitting on a sculpted ground plane. The ground plane has several particle systems setup on it: big and little trees (for a forest), two kinds of grass, some reeds around the edge of the pond. Then I have a camera that does a dolly move around the bank of the pond, while facing the building. The way the particle systems are setup is: a few parents and very many children that are generated at the time of render. All of the particles are static, (they don't change in any way through the extent of the dolly move).
So when rendering the ground plane particles have to be generated for EVERY frame of the animation even though the particles don't move or anything.
My question is this: is there a way for the children particles to be generated for the first frame and used again and again for the full duration of the animation?
I've done a lot of searching for baking in Blender, but that only has to do with textures (from what I've read). I've searched for "precompiling particles" but that didn't yield anything along the lines of what I was wanting. As you can tell, I'm not even sure what terminology I should be using. Any advice would be appreciated!
Here's a low frame-rate and "rough draft" of my animation: enter link description here
