Controlling the Particles with Deflectors
As you saw in the previous exercises, particles travel through a scene, guided by space warps but unaffected by geometry. Deflectors are a type of space warp that causes the particles that impact the deflectors to bounce as if they have collided with an immovable surface. The amount of bounce assigned to a deflector is a multiplier that defines the velocity of a particle after it impacts the space warp. A Bounce value of 0.5 results in the particle’s speed being reduced to 50 percent of the speed it had when it hit the deflector. Most deflectors have Time On and Time Off parameters that control when the deflector is active.
