Particles are rendered according to the material index of the emitter object, which is set on the Render
tab. You can also determine here whether the emitter itself will be rendered, whether parent particles will be
rendered,whetherunbornparticleswillberendered,andwhetherparticleswillberenderedaftertheyhavedied,
all by toggling the corresponding buttons in this area.
Using Force Fields and Deflection
Objects can influence the behavior of particle systems in two main ways, by using force fields and deflection,
which can be found in their respectively named tabs in the Physics buttons area.
Force Fields
Many natural forces, from wind to magnetism, can be made to act on particle systems by using
force fields
.
Force fields can be activated on any objects or added to the 3D scene directly through the Shift+A Add menu,
which is essentially equivalent to adding an Empty object with a force field active on it. In order for a force
field to act on a particle system, the force field object must be on the same layer as the object with the particle
