hi does anybody has a clue, how to realize a particle morph from "hard to liquid" ?:

i know how to move the particles that way. has anybody a suggestion how to solve the morphing issue?
or perhaps has any tutorial in mind, for this?

thx in advance

i assembled a demo scene for you. itīs a VERY simple setup since you now how to move and twist the particles your desired way (i guess the fume follow op would do a great job here!)...i donīt know if you have GLU3D so i used a BlobMesh instead so thereīs no further plugin needed...sorry for cheapness but my time is rare today. maybe the file leads you to a certain direction.

if not feel free to keep asking (auch auf deutsch, wenn du magst ;) )

max8 flow setup cheeeaaaaeap :D

kind regards

hey that is very cool thank you!!!
in fact i figured it out by myself, but i dont know how to make it look like a stream.
the blobs are ...well it look like in the old film "abyss" the living waterline, that flies through the boat.

it is not looking very dynamic like in the sketch
any idea?
glu3d is available

yeah th motion in my file (if thatīs what you mean) isnīt really one :D itīs moving along the icon arrow, thatīs all no forces no nothing...

okay, if a more proper meta shape like pwrapper is available you should be able to get nice shapes. concerning the motion it would be helpful to know what is happpening more pecise. on your image t looks like itīs kinda flushing and rolling. if itīs a more liquid kinda movement stick with glu and transfer the motion to pflow with a glu birth op maybe. i must admit that i havenīt tried this way yet since i donīt have a personal glu license and iīm not at work.
if itīs more a kind of puffy smoke-like rolling movement i would try to use FumeFX if thatīs available too. it has an op called "Fume FX Follow" which transfers the cached fume motion direct to flow (read the help for further details please).

with out a more proper fluid solver however i guess itīs quite hard to produce a convincing movement. you could try juggling with forces...

kind regards

thank you again psycho. i try glu the pwrapper of glu..but its all a bit ..well..blobby
i will ask another question in the main forum, about getting a kind of morphing effect, with a better picture.
it for the same job, but i bit more complicated. perhaps you have an idea for this?

thx

what kinda morphing? like this: http://www.core2core.de/spielwiese/schimmel2pretty.wmv ?

you should try to simulate the liquid with glu or if itīs more like smoke or something use fumeFX and then transfer the motion to pflow with pwrapper.

Hello.

I have a question concerning the link that you provided (morphing). I need to achieve an effect very similar to this one. I know how to do it with particle flow, but the problem is, that all the tutorials about morphing objects are based on models with very simple, one colour materials. Would this things work on objects with more complicated materials?

Let's say I'd like to morph a model of a car with multiple materials (metallic paint for car body, glass for windows, rubber for tires etc...) into another car with different materials.

Is it possible? And if it is, what is the way to achieve it?

hmm, i dont have a clue how to solve that.
perhaps you like to bake your object to just one material?

or create a third material, which describes the transition between those two different ones?

Dear b9999,

i would try allan mckayīs way of doing it: http://www.allanmckay.com/tut/tut_ObjAB.avi

if you involve particle flow toolbox#1īs mapping object i guess you could achieve your desired effect. maybe you could try boboīs way as well: http://www.scriptspot.com/bobo/mxs5/pflow/pflow__inherit_UV.htm

i guess the most cheapest way of solving the problem would be using an age test with a pretty high amount of variation. when you use a high amount of particles which change the object with a high speed and alot of force influence maybe even my cheap 1 minute trick i atached below would do the job...

good luck with your effect!
EDIT: youīd need box#1 to get correct results upon opening.

kind regards

Thank you very much PsychoSilence. I'll check your file as soon as I get home from work :) All methods look really promising I just need to pick the one that suits my needs the best :)
