UOmniFlect Space Warp

UOmniFlect, the universal omniflector, provides more options than the original UDeflector. This space warp lets you use any other geometric object as a particle deflector. The deflections are face accurate, so the geometry can be static, animated, or even morphing or otherwise deforming over time.

• Create panel > (Space Warps) > Deflectors > Object Type rollout > UOmniFlect button
• Default menu: Create menu > SpaceWarps > Deflectors > UOmniFlect
• Alt menu: Objects menu > Deflectors > UOmniFlect
• Alt menu: Simulate menu > Create (Simulation Set) > UOmniFlect

Note: Some particle “leakage” can occur with this deflector, particularly when you use many particles and a complex deflector object. To avoid this, perform a test render to check for leaking particles, and then add POmniFlects to catch the strays.

Procedures

To use the UOmniFlect space warp:

To use a universal omniflector, you need a minimum of three objects in the scene:

1. The particle system
2. The UOmniFlect space warp
3. The object used as the deflector
4. Add or select an object used as the deflector.
5. Create a particle system whose particles intersect the deflector object.
6. On the Create panel, click (Space Warps). Choose Deflectors from the list, then on the Object Type rollout, click UOmniFlect.
7. Click and drag in a viewport to place the space warp icon.
   Note: The size and position of the UOmniFlect icon do not alter the effect.
8. 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.
9. On the Modify panel Parameters rollout Object-Based OmniFlector group, click Pick Object, and then select the object to use as a deflector.
10. Adjust the particle system and UOmniFlect parameters as necessary.
