The current netview version does one kind of plotting that's useful for
many situations. It plots instances onto particle trajectories, providing
path-based motion.
The CGS_PlotParticles plugin plots particle global SRT values directly onto
the local SRTs of any selected objects or groups (scale is derived from
particle size). It also keyframes object visibility based on particle life.
But then I thought about all the times I would have liked to have accessed
other particle attributes to use for expressions, scripted ops, or
secondary simulation data. So the plugin will put a custom PPG on each
selected object and provide per particle info (**plotted):
* particleID
* typeID
* **Particle Life
* UVW origin coordinates
* **Size
* **Mass
* **Color
Every plot parameter is optional with a toggle switch available from the
plugin GUI.

How is this different from the one provided in the simulate

hey alex,<br><br>
brad just finished an "object to particles" plugin that we'll
be posting<br>
as<br>
soon as we iron out one problem with the documentation (of all
things!).<br>
it<br>
will attach geometry to particle trajectories and create fcurves
for<br>
them<br>
that you can tweak to your heart's content. it handles potential
memory<br>
problems by letting you dermine beforehand how many of the objects
xsi<br>
can<br>
reasonably handle before it becomes a problem.<br><br>
i'd be glad to send it to you...it may be the thing you're looking<br>
for...and<br>
to anyone else who wants to try it out before we officially
post.<br><br>
just email me offline,<br><br>

Good evening all,<br><br>
I am making a tree, I have modeled the branches et all...
And<br>
thought to add the leaves I would use particles. I have a good
effect<br>
going.<br>
I then freeze the particles, so there is no movement. create a
model<br>
from the tree geometry and the frozen cloud, then instance it so I
can<br>
make a nice big forest.<br><br>
however it is taking for ever to preview, I waited about five mins<br>
before the first block even appeared. and seeing as I only had
about<br>
twenty instances. its going to be a pretty rubbish forest !!<br><br>
Am I going about this the right way.. does anyone know of a better
way<br>
to add leaves without having to do it all by hand. It would be
lovely<br>
if I could convert the particles to geometry. But seeing as they
are<br>
instanced to begin with, I would imagine this isn't possible.<br><br>
any pointers would be a great help, as I am going to be stuck at
work<br>
all weekend working on this.<br><br>
thanks in advance<br><br>
