tyson helped me with this same problem a while back. the piece of geometry that is rebuilt is made using the shape mark operator.

ah nice! is that from the second DVD from allan? the DNA strand tut?

cheers

i don't know. I only have Allan's first DVD, and Tyson taught me this trick using Shape Facing. Maybe he learned it from Allan, I don't know.

so tell us the trick too

i think it┤s quite similar to allan┤s second dvd┤s first tutorial...

did you use particle studio my friend....i'v used sand blaster and the final is good so far.[img]images/icons/icon10.gif[/img]

and i am as far as you are. I just can't get the particles to rotate it the right position at the end. did you have perhaps any success?

may I also ask, if you did the fragmentation of the mesh first, and then import thes frags into PF, or have you found a way to fragment objects in PF directly?
I wrote my own slice based fragmentation script to avoid losing any volume. Then a modified form of Bobo's Scripted chunks. There is a sample fragmentation script for PFlow in the script reference that is ok. There's also a sample script in the reference for A to B and B to A that should work fine. Shouldn't take more than a couple days or less once I get the time. I'm obcessed with voxel scripting at the moment. So be patient.

nope, only particle flow

Quote: so tell us the trick too

well, its not really much of a trick, i guess. just using the tools. and i barely remember, since i haven't used Shape Mark since then! but I used Rivendale's Split It Up script to create chunks from my original geometry, cuz it's the best I've ever seen, and makes all the inside geometry accurately. I then set up a PFlow which used the grouped geometry chunks as particles, and when they hit the thing they were suppsed to be creating, they go to a new event which uses the shape mark operator to create a smooth patch of the textured geometry, so it looks like the chunk snapped into place. Worked perfectly!
For a better understanding, maybe read that thread i linked to, cuz that's where Tyson helped me work it all out. There's probably some details there I forgot. it's linked to in one of my previous posts.

Yeah! SPlitItUp is great! i use it in our current project (veeery early state of preview):

viewport preview:
http://www.core2core.de/spielwiese/...-moldy-test.avi

i think the toughest part is the proper target location for every particle (without illusion). in allan┤s tutorial they actually fit in their real position.

i┤ll see if i find my stipped file on that topic

cheers

ha, that was pretty cool!

the thing that surprised me most about the shape mark was the setting that made it look like it conformed to the geometry, which was the whole trick to "building" something out of particles. I can't remember what setting it was.

And yeah, Rivendale's script rules!

the trick is to frag your geometry then center the pivots of every fragment and reset the XForms.

then use this birth script:

Quote: on ChannelsUsed pCont do
(
pCont.useAge = true
pCont.useTM = true
pCont.useShape = true
)

on Init pCont do
(
global ChunksArray = $yourfragments_* as array
)

on Proceed pCont do
(
t = pCont.getTimeStart() as float

if t < 0 do
(
NumChunks = ChunksArray.count
for i = 1 to NumChunks do
(
pCont.AddParticle()
pCont.particleIndex = pCont.NumParticles()
pCont.particleAge = 0
pCont.particleTM = ChunksArray[i].transform
pCont.particleShape = ChunksArray[i].mesh
)
)
)

on Release pCont do
(

)


use the rename tool to rename your chunks to what every you like...
