How are these things created?

I just saw this demoreel from the frontpage and I was wondering how one could accomplish the grow effect from the 1st shot of the reel? Can something like that be created without scripting?

of course - good old fasioned tedious hand animating a mass of objects! :P

possibly even an extremely compicated and large pflow.

HMm, it must be Pflow according to the provided information on is site...

Smile might help

I had ALOT of questions on that scene.
Its pretty simple.
Basicly I just scripted the chuncks into pflow and scaled them to zero. then i had some deflectors come along and tell the chunks to rotate and scale to there original size.
This is were i learnt how to script pflow and fragments.

I put a stripped version of the file HERE

Please dont use the file for anything more than tearing apart.
Hope it helps.
Best regards

Wow! Thank you very much for sharing that! I saw your reel and was also wondering how you did that. Any chance you might wanna give a brief rundown of your particle view layout?
I think I get the jist of it, but I'm just curious how things like your gotorotation, find target, and keep apart work together for the effect. Thanks for the info.

(Ive attached a screen grab of your particle view.)

Bump, in hopes of a brief explanation.

Old 02 February 2007   #13
so...i have been able to kinda figure this out by toying around with it. but i am pretty new to particle flow and even newer to maxscript, so that doesnt really mean i fully understand what is going on...i have atatched a screenshot of my PF which works but geeks out around frame 50 and i can not get it to work without the script operator being before the birth operator..also, if any one could maybe shine a little light on how this is working, i would greatly appreciate it..not trying to ask dumb questions, but i can get it to work and have a slight understanding, but any additional info on how this PFlow is thinking (so to speak) would be amamzing..thanks and much respect for even giving me this much info and actually sharing your file..many thanks

Some info

Hey dudes.

prox-emics - happy to share.
t1042 - lookin sweet.

Been very busy so I didnt see that this thread was still active.
I made this flow a year ago so Im gonna try to explain it if I remember it right.
Might have done this diffrently today but it works so whatever.
(The Event numbers are a bit weird so just see them as names).

Event 01
This event gets all the fragments from the scene and puts them in the flow.
I scale the particles down to zero so you cant see them.
The rotation doesnt do anything the birthscript isnt already doing so you dont need it.
Then I let a couple deflector tell pflow to go to the next event

Event 02
Here i put the position of each particle into the particle vector and send them to Event 05
I did this so i can move the particles with forces or a keep apart
and then let it find their way back to their original position with a find target.

Event 05
Then I animate the scale up to its normal size. I push them apart with the keep apart.
I also use the go to rotation to find a random 3d rotation under 7 frames and then
send the particles to event 06

Event 06
here the particles finds its way back to its original rotation (go to rotation & rotation)
and its original position with the findtarget set on script vector from Event 02

Event 07
Kills the speed and I have a Delete in there cause I was probably experimenting with a particle age material.

Thats should be it.
Hope that explains it a bit clearer.
Best regards
