Limiting particle speed

There are three ways to control speed of particles. You can use POP Drag DOP, POP Speed Limit DOP, or POP Wind DOP nodes.

To...	Do this
Apply drag to particles	Click the Drag Particles button on the Particles shelf tab. Select the particle system you want to be affected and press `Enter` to confirm your selection.
Set a high and low limit on the speed of particles	Create a POP Speed Limit DOPnode in the particle network. Use the Minimum Speed and Maximum Speed parameters, to set the velocities. Each particle can have its own set of imposed limits.
Push particles up to, but not past, a certain speed	Click the Wind on Particles button on the Particles shelf tab. Select the particle system you want to be affected and press `Enter` to confirm your selection. The POP Wind DOP simulates a pushing force like wind that can increase the velocity of particles but not past its own speed. Set the Wind Velocity to control the direction and magnitude of the wind, and the Air Resistance to control the intensity of the wind.
