This is a modified version
of the standard wind modifier that ships with max. The update primarily
affects how the turbulence operates, although falloff for wind has
been modified too.
The primary aim was to add falloff for the turbulence
since the falloff only affected wind, but I ended up adding some
other stuff too since that was a two line fix...
Turbulence - as it was.
Frequency - as it was
Scale - as it was but broken out into world
X Y Z. Use the 'lock to X scale' to just use the X value to control
all 3 axes.
Phase - in the original warp modifier having
the frequency at a non-zero value would automatically cause the
noise to 'phase' over time - this parameter has been detached from
time and broken out to XYZ.
Decay is as it was. Newly added is Start/End, and between these
two you get some control over the falloff: linear, smoothstep or
Mask Planar Falloff allows you to limit a planar icons falloff using
a radial falloff in addition to either decay or start/end falloff.
In the original, the affect of the warp was infinite on the plane
of the icon.
Noise3 is the original
Turbulence does nothing yet.
fBm1 is fractal brownian motion and uses the H, Lacunarity and Octaves
to control the noise. You can find out what these do if you look
around the net for fBm info.
Noise4 is the same as noise3 with an additional Phase parameter,
which uses just the first control in the fBm/Noise4 control group
to control this.
These affect some of the algorithms, see above.
Display is as it was, updated for the additional
I added a bunch of features a while back, but haven't documented them,
and I'm no longer exactly sure what some of them do - trial and error
will sort you out. Keep distance tried to keep the particles a set
distance from a node, you can get interesting effects using this and
driving the particles around the distance-sphere using noise. Like:
- 'Turbulence' algorithm does nothing useful
(I'll look at this at some stage)
- UI elements don't grey out when they should.
- Range Indicators leave drit on screen (just need to modify the
bounding box code methinks), redraw views to clean up.
- To disable falloff entirely, set to 'Decay' mode with decay of
0.0 - I plan to add an 'enabled' checkbox at some stage.
- XYZ's are world based, I'd like them to be icon based at some

The 2009 version has has the display of the ranges fixed - it never
calculated it bounding box correctly before so the falloff ranges could
mess up your display a little.
Note that no R5 version is currently available
- I'll compile an R5 one if I get enough interest.
Unzip and copy the downloaded .dlm to your plugins
directory then restart max.
Contact firstname.lastname@example.org with any bug info.
Scene files demonstrating problems are much easier to troubleshoot.
