Maya 2016 / nParticle Instancer / Make a goal for each particle to its own instance

[francois bonnard]

Hello Guys

Excuse my french. Here is the case :

1. I have created 220 particles with a first goal. (a curve)  

2. Particle instancer : each particle is linked with its own instance 

-> runtime  after dynamics :

if (nParticleShape1.age>4)

{

nParticleShape1.MyIndex = nParticleShape1.particleId +1;

}

3. Now I would like to assign for each particle a new unique goal, which is the position of its "instance plane" 

I have attached the file and here is a rendered picture. You can see the bouquet of Particle above, and below the original plane which were used for the particle instancer. Actually i would like that each particle matches with its original plane (hope it is clear)

Any idea ?

Thanks

François

do you have 2016.5? if so you could do that with Mash in no time.

Sounds like SOuP would help you out here. You can use the mesh2arrays node to create your unique plane positions then store these as PP birth goalU, goalV values for each particle. You'll likely need to use a closest UV on mesh to get these initial values though as, from memory, mesh2arrays doesn't provide that. The SOuP scatter node may also be helpful for this.

If you aren't too fussy about the proximity of the particles (to each other) on your plane I think that even the humble Maya emitter has some overlap culling that could be used for this.
