Procedure
Many dy naflector parameters are the same as
those for omniflectors. However, the procedure
of associating the dynaflector with both the
particle system and the object to be affected is
more complex than the simple binding used by
omniflector.
To create a parti cle/dyn amics system:
1.
Create or load a scene containing a
non-event-dr iven particle system (page 2–237)
and an object to be affected by the particles
(hereafter c alled "the object"). Position and
orient the two as desired so that the particles
strike the object.
• The icon for the particle system must be
visible in at least one non-disabled viewport.
• On the Basic Parameters rollout of the
particle system, set Percentage of Particles
to 100%. Otherw ise, only those particles
displayed in the viewport w ill be calculated.
2. OntheCreatepanel,click
SpaceWarps. ChooseDeflectorsfromthe
drop-down list, and then click one of the
dynaflector buttons (PDynaFlect, SDynaFlect,
or UDynaFlect). Drag in a v iewport to create
the deflector.
3. Do either of the following:
• If using a PDynaFlect or SDynaFlect,
position the space warp icon where the
particles strike (or w i ll strike) the object.
Resize and orient it as needed.
Also, link the PDynaFlect or
SDy naFlect as a child of the object. This
step isn’t absolutely necessary, but al lows the
deflector to follow the object as it moves.
• If using a UDynaFlect, go to the Modify
panel > Parameters rollout, click the Pick
Object button, and then select t he object.
Thepositionofthespacewarpicondoesn’t
matter, and it’s not necessary to link the two.
4. Bind the particle system to the
dynaflector using the toolbar Bind to Space
Warp button (page 2–58).
5. Go to the Utilities panel and open the
Dynamics utilit y.
6. OntheDynamicsrollout,clickNewtocreatea
new simulation.
7. ClickEditObjectList,andaddtheobjecttothe
dynamics simulation.
8. ClickEditObject.OntheEditObjectdialog,
click Assign Object Effects and assign the
dynaflector to the object.
Note: Because only those particles displayed
in viewports are used in the dy naflector
calculations, solving the dynamics involves
three requirements:
9. On the Dynamics rollout, turn on the Update
Display w/S olve check box above the Solve
button.
10. Solve the simulation.
