Baking
It is possible to store the calculations for the particle simulation, so that the animation can be sped up in subse-
quent viewings. To do this access the Cache tab in the Particle properties area. To bake the simulation, simply
enter the start and end frame values for the time segment you want to bake and click the Bake button. Once
baked, the basic particle properties for the system will no longer be editable. If you want to adjust these proper-
ties, you will need to click the Free Bake button that replaces the Bake button on the same tab.
Physics
The Physics tab contains the fields that most directly influence the way the particles interact with the forces in
the world. There are five options in the Physics drop-down menu: No, Newtonian, Keyed, Boids, and Fluid.
