The Drag space warp is a particle motion damper
thatreducesparticlevelocitybyaspecifiedamount
withinaspecifiedrange. Thedampingcanbe
applied linearly, spherically, or cylindrically. Drag
is useful for simulating wind resistance, transfers
into dense media (like water), impacts with force
fields, and other, similar situations.
With each damping type, you can control the
damping effect along several vectors. The damping
is also affected by part icle system settings, such
as speed.
Note: To c reate a more u n i for m d r ag effe c t,
default values for all directional parameters are
now 5.0%.
Drag slows down a s tream of particles.
Procedure
To create a Drag space warp:
1.
On the Create panel, click Space
Warps. Choose Forces from the list, and t hen
click Drag.
2. Drag in a viewport to create the space warp.
The space warp appears initial ly as a box within
a box, indicating that it’s using the default
Linear Damping mode.
3. To apply the damping spherically or
cylindrically, choose Spherical Damping or
Cylindrical Damping in the command panel.
Note: The position and orientation of the space
warp plays an important role for al l three
damping typ es.
4. Change the setti ngs for the c urrent damping
type as necessary.
