UDeflector

The UDeflector is a universal deflector that lets you use any object as a particle deflector.

Particles scatter when they strike a UDeflector object

Procedures

To create a UDeflector:

On the Create panel, click (Space Warps). Choose Deflectors from the list, then on the Object Type rollout, click UDeflector.
In a viewport, drag out a rectangle to add a UDeflector warp to the scene.
On the command panel, click the Pick Object button and select an object to be a particle deflector.
Apply the deflector to the particle system using the appropriate method:
- If using Particle Flow, specify the deflector in the Collision test or Collision Spawn test parameters.
- If using a non-event-driven particle system, bind the particle system to the deflector icon.
Position the UDeflector icon to interrupt the particle stream.
Adjust the UDeflector parameters as necessary.

Interface

Object-Based Deflector group

Specifies the object to use as a deflector.

Item: Displays the name of the selected object.
Pick Object: Click this, and then click any renderable mesh object to be used as a deflector.

Particle Bounce group

Bounce: Determines the speed with which particles bounce off the deflector. At 1.0, the particles bounce at the same speed as they approach. At 0, they don't deflect at all.
Variation: The amount by which each particle can vary from the Bounce setting.
Chaos: The amount of variation from the perfect angle of reflection (found when Chaos is set to 0.0). 100% induces a variation in reflection angle of up to 90 degrees.
Friction: The amount by which particles are slowed as they move along the deflector surface. A value of 0% means they're not slowed at all. A value of 50% means they're slowed to half their original speed. A value of 100% means they stop moving when they strike the surface. Default=0%. Range=0% to 100%.

TipTo have particles slide along a deflector surface, set Bounce to 0. Also, unless influenced by a force such as Wind or Gravity, particles meant to slide should strike the surface at an angle other than 90 degrees.
Inherit Vel: (Velocity Inheritance) When greater than 0, the motion of the deflector affects particles as well as the other settings. For example, to animate the SDeflector passing through a passive array of particles, turn up this value to affect the particles.
